    Hadoop
    is most popular and powerful big data tool.
    It provides
    1-HDFS ->>(WOLRD MOST RELIABLE STORAGE LAYER)
    2-MAPREDUCE->>(DISTRIBUTED PROCESSING)
    3-YARN->>(RESOURCE MANAGEMENT LAYER)

    There are some features of Hadoop listed below:

    1-DEADLOCK->Hadoop will never go under Deadlock condition.

    2-OPEN-SOURCE->It means that we can modify the source code upon our business requirement and it will open the gate for the researcher.

    3-DISTRIBUTED PROCESSING->Data is stored in a distributed manner so that data is processed parallel on a cluster of nodes.

    4-FAULT TOLERANCE->It can store 3 replicas by default on different datanode of the different rack so if any node goes down, data on that node will be recovered from other nodes.

    5-RELIABILITY->Data is stored reliably on a cluster of the machine due to replication of data in the cluster.

    6-SCALABILITY->It provide horizontal scalability so that new hardware can easly added to nodes.

    7-HIGH AVAILABILITY->It means available in worst condition.it will never show a message that DATA IS NOT AVAILABLE.

    8-ECONOMIC->it runs on commodity hardware so it is not expensive.

    9-EASY TO USE->It will perform distributed processing by himself.

    10->DATA LOCALITY->it run DATA LOCALITY principle which state that move computation to data instead of data to computation.
