Subject [jira] [Created] (HBASE-15357) TableInputFormatBase getSplitKey does not handle signed bytes correctly

-------------------------------------

             Summary: TableInputFormatBase getSplitKey does not handle signed bytes correctly
                 Key: HBASE-15357
                 URL: https://issues.apache.org/jira/browse/HBASE-15357
             Project: HBase
          Issue Type: Bug
          Components: mapreduce
            Reporter: Nathan Schile
            Assignee: Nathan Schile


When auto-balance is enabled in TableInputFormatBase and the table key is a binary key, the
getSplitKey method does not function correctly for signed bytes. The proposed solution it
to utilize org.apache.hadoop.hbase.util.Bytes#split method to find the split key. org.apache.hadoop.hbase.util.Bytes#split
is stated to be a expensive operation, so if another solution is preferred, that is fine.
In addition, handling of a split key that is equal to the TableSplit end key is added to calculateRebalancedSplits.
