Zhihong Yu commented on HBASE-5636:
-----------------------------------
A careful check of the failed test:
https://builds.apache.org/job/PreCommit-HBASE-Build/1369/testReport/junit/org.apache.hadoop.hbase.mapreduce/TestMultithreadedTableMapper/testMultithreadedTableMapper/
would reveal the following:
{code}

This should have been fixed by MAPREDUCE-3583
Once hadoop 1.0.2 comes out, we won't see the above exceptions.
> TestTableMapReduce doesn't work properly.
