> When debugging MR jobs reading from hbase table, it's import to figure out which region
a map task is reading from.
> But the table split object is hard to read.
> eg:
> {code}
> 2014-09-01 20:58:39,783 INFO [main] org.apache.hadoop.mapred.MapTask: Processing split:
lg-hadoop-prc-st40.bj:,0
> {code}
> See: TableSplit.java 
> {code}
>   @Override
>   public String toString() {
>     return m_regionLocation + ":" +
>       Bytes.toStringBinary(m_startRow) + "," + Bytes.toStringBinary(m_endRow);
>   }
> {code}
> We should make it more readable.
