Hadoop clusters also are known as “Shared Nothing” means no data shared between Hadoop clusters. The shared nothing paradigm of a Hadoop cluster reduces the processing latency therefore once there's a necessity to method queries on huge amounts of information the cluster-wide latency is totally decreased.

Main Components of Hadoop Clusters are Master Node, Worker Node, and Client Nodes.

What is Spark in Hadoop?

Spark also open source framework and mainly used for data analytics. Spark runs faster than Hadoop and is designed on top of the Hadoop. Spark does not have a separate file system and it integrated with another one. The main feature of spark does not use YARN for functioning. Spark does not have own file system for processing data because programmers install spark at top of the hadoop.

Types of Big Data Tools
  • Cassandra
  • MongoDB
  • Neo4J
  • Storm
  • Hive
Main Functions of Hadoop
  • hdfsshell() function – This function helps to invoke the HDFS
  • LoadJobConf() function – This function helps to describe the MapReduce Jobs
  • MapReduce() function – It used to run the MapReduce jobs
  • native MR() function – This function helps to Lanches MapReduce jobs
  • readConf() function – This function returns name value from current Hadoop Jobconf
Meaning of Hadoop Ecosystem

Hadoop ecosystem is not a service and programming, Hadoop ecosystem is the one type of platform which used to process a large amount of Hadoop Data. Hadoop ecosystem using HDFS and MapReduce for Storing and processing a large amount of data and also used Hive for querying the data.
