We have a backport copy of o.a.h.mapreduce.lib.partition.InputSampler in HBase which contains a bug, MAPREDUCE-1820. This JIRA is to update our copy to the version in MR trunk.
Produced patch by copying new source from MR trunk.
Bringing into 0.90.1. Will commit to 0.90 if the current RC doesn't make the grade.
Committed to branch and trunk
Integrated in HBase-TRUNK #1701 (See https://hudson.apache.org/hudson/job/HBase-TRUNK/1701/)
