Ankit Singhal updated PHOENIX-2671:
-----------------------------------
Attachment: PHOENIX-2671.patch
[~jamestaylor], PFA, for review.
Problem is with doing checkAndPut on EMPTY_BYTE array as hbase consider that as
also null.
{code}
HRegion.class
@Override
public boolean checkAndMutate(byte [] row, byte [] family, byte [] qualifier,
CompareOp compareOp, ByteArrayComparable comparator, Mutation w,
boolean writeToWAL)
throws IOException{
...
else if (result.size() > 0 && result.get(0).getValueLength() == 0 &&
valueIsNull) {
matches = true;
}
{code}
Have raised the jira HBASE-15260 to either remove this check or fix the
documentation.
Attached patch should also fix the SYSTEM.CATALOG timestamp to
MIN_SYSTEM_TABLE_TIMESTAMP_4_7_0 after upgrade.
