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.
Integrated in HBase-TRUNK #1701 (See https://hudson.apache.org/hudson/job/HBase-TRUNK/1701/)
HBASE-3392. Update backport of InputSampler to reflect MAPREDUCE-1820
Committed to branch and trunk
Bringing into 0.90.1. Will commit to 0.90 if the current RC doesn't make the grade.
Produced patch by copying new source from MR trunk.
