ramkrishna.s.vasudevan commented on HBASE-11440:
------------------------------------------------

The bug is not because of the new codec.  The bug is because when we add this 
configuration and say KeyValueCodec only as the replication codec still this 
test fails here.

Adding this property in hbase-default.xml causes this issue.  Will check and 
come back on this if this is a Testcase only issue or a real issue.

> Make KeyValueCodecWithTags as the default codec for replication in trunk
