Spark is a cluster computing framework designed to be fast, general-purpose, and able to handle a wide range of workloads including batch processing, iterative algorithms, interactive queries, and streaming. It is faster than Hadoop for interactive queries and complex applications by running computations in-memory when possible. Spark also simplifies combining different processing types through a single engine. It offers APIs in Java, Python, Scala and SQL and integrates closely with other big data tools like Hadoop. Spark is commonly used for interactive queries on large datasets, streaming data processing, and machine learning tasks.
This document provides an overview of Spark SQL and its architecture. Spark SQL allows users to run SQL queries over SchemaRDDs, which are RDDs with a schema and column names. It introduces a SQL-like query abstraction over RDDs and allows querying data in a declarative manner. The Spark SQL component consists of Catalyst, a logical query optimizer, and execution engines for different data sources. It can integrate with data sources like Parquet, JSON, and Cassandra.
The document discusses YARN (Yet Another Resource Negotiator), which is the cluster resource management layer of Hadoop. It describes the limitations of the previous Hadoop 1.0 architecture where MapReduce was responsible for both data processing and resource management. YARN was created to address these limitations by separating resource management from data processing. It discusses the components of YARN including the Resource Manager, Node Manager, Containers, and Application Master. It also provides examples of workloads that can run on YARN beyond MapReduce and describes the YARN architecture and how applications run on the YARN framework.

Tame the small files problem and optimize data layout for streaming ingestion...Flink Forward
Flink Forward San Francisco 2022.
In modern data platform architectures, stream processing engines such as Apache Flink are used to ingest continuous streams of data into data lakes such as Apache Iceberg. Streaming ingestion to iceberg tables can suffer by two problems (1) small files problem that can hurt read performance (2) poor data clustering that can make file pruning less effective. To address those two problems, we propose adding a shuffling stage to the Flink Iceberg streaming writer. The shuffling stage can intelligently group data via bin packing or range partition. This can reduce the number of concurrent files that every task writes. It can also improve data clustering. In this talk, we will explain the motivations in details and dive into the design of the shuffling stage. We will also share the evaluation results that demonstrate the effectiveness of smart shuffling.

Brief Introduction about Hadoop and Core Services.Muthu Natarajan
I have given quick introduction about Hadoop, Big Data, Business Intelligence and other core services and program involved to use Hadoop as a successful tool for Big Data analysis.
My true understanding in Big-Data:
“Data” become “information” but now big data bring information to “Knowledge” and ‘knowledge” becomes “Wisdom” and “Wisdom” turn into “Business” or “Revenue”, All if you use promptly & timely manner
Big Data Warsaw v 4 I "The Role of Hadoop Ecosystem in Advance Analytics" - R...Dataconomy Media
What is Big Data? What is Hadoop? What is MapReduce? How do the other components such as: Oozie, Hue, Hive, Impala works? Which are the main Hadoop distributions? What is Spark? What are the differences between Batch and Streaming processing? What are some Business Intelligence Solutions by focusing on some business cases?
Big data is a combination of structured, semi-structured and unstructured data collected by organizations that can be mined for information and used in machine learning projects. Systems that process and store big data have become common in organizations, combined with tools that support big data analytics uses such as improving operations, providing better customer performance, and creating personalized marketing campaigns. Hadoop is an open-source framework for distributed storage and processing of large data sets across clusters of computers. It includes projects like HDFS, MapReduce, YARN, and common utilities.
The document provides an overview of Hadoop, including:
- What Hadoop is and its core modules like HDFS, YARN, and MapReduce.
- Reasons for using Hadoop like its ability to process large datasets faster across clusters and provide predictive analytics.
- When Hadoop should and should not be used, such as for real-time analytics versus large, diverse datasets.
- Options for deploying Hadoop including as a service on cloud platforms, on infrastructure as a service providers, or on-premise with different distributions.
- Components that make up the Hadoop ecosystem like Pig, Hive, HBase, and Mahout.
Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

3. RDBMS
Stands for ‘Relational Database Management
System’
It is a database that stores data in a structured
format using rows and columns.
One can execute queries on the data like
adding, updating, and searching for values.
It also provides a visual representation of the
data.
It is "relational" because the values within each
table are related to each other.
The relational structure makes it possible to run
queries across multiple tables at once.
Structured Query Language is the standard
programming language used to access the
database.
ADVANTAGES
Addresses the need for integrating,
managing and analysing data from
multiple sources across on-
premises and cloud environments
Ease to locate and access specific
values within the database
High flexibility due to storage,
retrieval and publishing of JSON data
within a relational database
EXAMPLES
4. It is a matter of the past when data were limited.
Now, the world has already experienced the power
of Big Data, and the same is used to analyze to
frame different business strategies and others.
Apache Hadoop is one of the kinds of open-
source platforms that we can use to store and
process relatively large datasets amounting from
gigabytes to petabytes. This open-source allows
multiple computers to make clusters and analyze
the large datasets in parallel and effectively.
5. Four main
components
of
the Hadoop
ecosystem:
HADOOP DISTRIBUTED FILE SYSTEM (HDFS)
A primary data storage system that runs on commodity
hardware and manages enormous data collections. It
also has a high data throughput and a high fault
tolerance.
YET ANOTHER RESOURCE NEGOTIATOR (YARN)
YARN is a cluster resource manager that schedules
tasks and assigns resources (such as CPU and memory)
to applications.
1
2
3
HADOOP MAPREDUCE
Breaks down the big data processing tasks into smaller
ones, distributes them across different nodes, and then
runs each one.
4
HADOOP COMMON (HADOOP CORE):
A collection of common libraries and utilities on which
the other three modules rely.
6. Importance
of
Hadoop
Ability to quickly store and handle large amounts of any type of data
That's an important concern as data volumes and varieties continue to grow, notably from social
media and the Internet of Things (IoT).
Computer processing power.
Hadoop's distributed computing model efficiently processes large amounts of data. The more
computing nodes you use, the more processing power you have.
Fault tolerance
Data and application processing are protected against hardware failure. If a node fails, jobs are
automatically transferred to other nodes, ensuring that the distributed computing does not fail.
Multiple copies of all data are stored automatically.
Flexibility
Unlike traditional relational databases, we don’t have to preprocess data before storing it. We can
store as much data as we want and decide how to use it later. It includes unstructured data like text,
pictures, and videos.
Low cost
The open-source framework is free and stores large amounts of data by using commodity
hardware.
Scalability
By simply adding nodes, we can easily expand our system to handle more data. A little administrative
is required.
7. Challenges in using Hadoop
1 MAPREDUCE PROGRAMMING ISN'T SUITED FOR EVERY PROBLEM
It performs well for simple information requests and problems that can be broken down into independent units, but it is
inefficient for iterative and interactive analytic operations. MapReduce is file-intensive. Iterative algorithms require
multiple map-shuffle/sort-reduce phases to complete because the nodes mainly communicate through sorts and
shuffles. This results in so many files being created between MapReduce phases, which is inefficient for advanced
analytics computing.
2
It can be difficult to find entry-level programmers who have adequate Java expertise to be productive with MapReduce.
That's one reason distribution providers are racing to put relational (SQL) technology on top of Hadoop. Programmers
with SQL skills are easy to find than MapReduce skills. And, Hadoop administration seems a mix of art and science,
requiring a basic understanding of operating systems, hardware, and Hadoop kernel settings.
THERE’S A WIDELY ACKNOWLEDGED TALENT GAP
3
Another concern is the fragmented data protection challenges, which are being handled by new tools and technology.
The Kerberos authentication protocol is a significant step toward securing Hadoop environments.
DATA SECURITY
4
Hadoop lacks user-friendly, full-featured tools for data management, data cleansing, governance, and metadata services.
FULL-FLEDGED DATA GOVERNANCE AND MANAGEMENT
8. Apache Spark began in 2009 as a research project at UC Berkeley's AMPLab focused on data-
intensive application areas.
Apache Spark is an open-source, distributed processing system used for big data workloads.
For rapid analytic queries against any quantity of data, it uses in-memory caching and efficient
query execution.
It allows code reuse across different workloads—batch processing, interactive queries, real-
time analytics, machine learning, and graph processing—and provides development APIs in
Java, Scala, Python, and R.
Spark's objective was to build a new framework that was optimised for quick iterative
processing, such as machine learning and interactive data analysis, while preserving Hadoop
MapReduce's scalability and fault tolerance.
The primary importance of Apache Spark in the Big data industry is because of its in-memory
data processing that makes it a high-speed data processing engine compared to MapReduce.
Apache Spark delivers a better-integrated framework which supports all ranges of Big data
formats like batch data, text data, real-time streaming data, graphical data, etc.
