Spark and Map Reduce Component of Hadoop

• In this Article we will see about the Map reduce
  and Spark. We will see how the spark is powerful
  and replacing the map reduce. Spark is the
  powerful framework which must be the part of the
  Hadoop Training in modern classroom.

3
Map Reduce in Hadoop

• Two main Hadoop Components are HDFS and Map
  Reduce. Mapreduce is the processing unit of
  Hadoop.
• Big data which was stored in HDFS which will not
  be in classical data format. It will be stored in
  separated data nodes.

4
Map Reduce advantage

• It is extensively used in so much of areas such
  as Index, searching, Analytics, various
  classifieds, recommendation engine.
• For Example, Amazon, Flipkart and in much more
  e-commerce provide recommendation of similar
  products. While you purchase a particular product
  lot of similar and recommended products will be
  displayed along with your product. This is
  parallel processing strength.

5
Apache Spark - Introduction

• Apache spark is an open source software which is
  very flexible In memory framework. The unique
  quality of this Apache Spark compute engine is
  like, it allows the same unified framework to do
  the batch interactive jobs on the cluster.

6
Learn about RDD

• We need to understand the RDD before starting the
  introduction about SPARK. RDD is Resilient
  Distributed Datasets.
• We can extract the data from system in object
  format. We can do the computation on top of
  object format. The building blocks of RDD are
  lineage graphs.

7

• Lazy evaluation is one of the major interesting
  factor in RDD.
• For Example, Reading the CSV file will create the
  RDD.First statement which will execute the read
  of CSV will point out that particular file. It
  will not load the entire data into the memory. If
  user wants to search Hadoop Training in whole
  big data.

8
Benefits of SPARK

• Fault recovery using lineage is the major
  benefit. In-Memory computation is the main
  benefits in Spark.It will use the Directed
  Acyclic graph.Easy for programming since it will
  be transformation and actions using RDD. Very
  rich library support for machine learning,
  Graphix, Data Frames. In real time financial
  sectors are the huge customers for Spark.

9
Mapreduce VS Spark

• Spark address the performance challenges very
  well compared to Map Reduce
• Map Reduce need Lots of Java Code and difficult
  API interactions. In other hand Spark API is very
  well designed.
• We need to split the huge job into so much of
  smaller job in Map Reduce. Spark will execute the
  huge job in much better parallel form compared to
  Mapreduce.

10

• Spark will support Python, Scala and other
  popular languages.
• Spark architecture is uniquely well suited for
  streaming processing, stream engine
• Nowadays, Hive, Pig, Sqoop are migrating from the
  Mapreduce to Spark in Hadoop ecosystem.
