Do Hive replicates data on HDFS?

    Hi All,

    I am new to Hadoop technology. Actually I have a confusion on Hive. I know that whatever data we write in Hadoop, it gets replicated on each data node. But, do it happen in case of Hive. I mean, when we create a table in Hive, does it also get replicated on all data nodes?.
    Please help

    Thanks in advance,

    By default, data is replicated to 3 nodes. This can be controlled system-wide or for individual files / directories using the command “hadoop fs -setrep”
