Enis Soztutar commented on HBASE-12600:
---------------------------------------
This looks good.
Can you please add a comment here, so that 3 is not used again as a tag byte.
{code}
- public static final byte LOG_REPLAY_TAG_TYPE = (byte) 3;
{code}
> Remove REPLAY tag dependency in Distributed Replay Mode

> After HBASE-11315 & HBASE-8763, each edit has a unique 'version' i.e. its
> SequenceId(or old mvcc value). Therefore, we don't need replay tag to handle
