Description

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:

2014-09-01 20:58:39,783 INFO [main] org.apache.hadoop.mapred.MapTask: Processing split: lg-hadoop-prc-st40.bj:,0

See: TableSplit.java

  @Override
  public String toString() {
    return m_regionLocation + ":" +
      Bytes.toStringBinary(m_startRow) + "," + Bytes.toStringBinary(m_endRow);
  }

We should make it more readable.
