stack commented on HBASE-2195:
------------------------------
bq. The trick with with deserializing previous versions would still work; but
only because we are not actually using any methods from VersionedWritable
(HLogKey.readFields() does not call super.readFields and HLogKey.write does not
call super.write.)
Yes. Exactly. Given this, I'd say subclassing VersionedWritable would only
confuse since you are not making full use of it.

> We need to support cyclic replication by using the cluster id of each HlogKey
