>
> 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.
