    hi to all,
    Good Morning,
    I had a set of 22documents in the form of text and loaded in hdfs,when running a map/reduce funtion from command line of hdfs ,it took 4mins 31 secs for streaming the 22 text files.How do increase the map/reduce process as fast as possible so that these text files should complete the process by 5-10 seconds.
    What changes I need to do on ambari hadoop.
    Allocated 2GB of data for Yarn,and 400GB for HDFS
    default virtual memory for a job map-task = 341 MB
    default virtual memory for a job reduce-task = 683 MB
    MAP side sort buffer memory = 136 MB
    And when running a job ,Hbase error with Region server goes down,Hive metastore status service check timed out.

    Thanks & regards,
