    We are having MR job which reads the Table’s data, after performing some operations commits the data back.
    We are having two regions servers and The table is having 20milion records on two Machines in 15 regions ( 8 regions on Machine1 and 7 regions on Machine2).
    When we run the MR job,Some Mappers on Machine1 are reading the regions on Machine2. This is causing the MR job to take hours of time to complete.

    The mappers are reading like this every time.

    Can someone help us on this.
