    Hi,

    We need to read Hbase table rows of volume about 100Million.
    For mapper, It is taking 2 minutes to read 1Lakh rows on a single machine.
    We are using “TableMapReduceUtil” for reading from the Hbase table.

    Could you please help us to tune this job.

    Thanks,
    SambaShiva
