sri commented on HBASE-12445:
-----------------------------
In the ProtoBufUtil.toMutation(final MutationType type, final Mutation
mutation, MutationProto.Builder builder, long nonce)
QualifierValue.Builder valueBuilder = QualifierValue.newBuilder(); at line
number 1110 should be inside the inner for loop at 1115 or needs to clear the
ValueBuilder. Otherwise valueBuilder is carrying over the previous values that
where set. In this case the DeleteType is getting carried over to the next
columns and deleting all the columns.
> hbase is removing all remaining cells immediately after the cell marked with
> marker = KeyValue.Type.DeleteColumn via PUT
