DistCp does not honour config-overrides for mapreduce.[map,reduce].memory.mb

    • Bug
    • Status: Resolved
    • Major
    • Resolution: Fixed
    • 0.23.9, 2.2.0
    • 3.0.0-alpha1
    • distcp
    • None
    • Incompatible change
    • Prior to this change, distcp had hard-coded values for memory usage. Now distcp will honor memory settings in a way compatible with the rest of MapReduce.

    Description

      When a DistCp job is run through Oozie (through a Java action that launches DistCp), one sees that mapred.child.java.opts as set from the caller is honoured by DistCp. But, DistCp doesn't seem to honour any overrides for configs mapreduce.[map,reduce].memory.mb.

      Problem has been identified. I'll post a patch shortly.
