HConstants.MAX_ROW_LENGTH is incorrectly 64k, should be 32k
-----------------------------------------------------------

                 Key: HBASE-1895
                 URL: https://issues.apache.org/jira/browse/HBASE-1895
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.0
            Reporter: ryan rawson
             Fix For: 0.20.1, 0.21.0


the max length of a row has to fit into a signed short. That is 32k.  The constant is incorrect,
but in the depths of KeyValue it does the right thing:

    if (rlength > Short.MAX_VALUE) {
      throw new IllegalArgumentException("Row > " + Short.MAX_VALUE);
    }

so your Put wont fail and instead it will fail in the KeyValue constructor.  So far only that
1 line in Put uses this constant, but we should have a correct value here.
