> Key: HBASE-5345
> URL: https://issues.apache.org/jira/browse/HBASE-5345
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.92.0
> Reporter: Evert Arckens
> Assignee: Evert Arckens
> Fix For: 0.94.0, 0.92.1

>
> When a value contains an empty byte[] and then a checkAndPut is performed
> with an empty byte[] , the operation will fail.
> For example:
> Put put = new Put(row1);
> put.add(fam1, qf1, new byte[0]);
> table.put(put);
> put = new Put(row1);
> put.add(fam1, qf1, val1);
> table.checkAndPut(row1, fam1, qf1, new byte[0], put); ---> false
> I think this is related to HBASE-3793 and HBASE-3468.
> Note that you will also get into this situation when first putting a null
> value ( put.add(fam1,qf1,null) ), as this value will then be regarded and
> returned as an empty byte[] upon a get.
