Lars Hofhansl commented on HBASE-2195:
--------------------------------------
The version in WALEdit is final, though, and there is no constructor setting it.
The fact that it is not static looks like a oversight.
I disagree with the latest patch. The version in HLogKey should be a class
version. That is the whole point of VersionedWritable.
Having an instance version only makes sense if the write would behave
differently based on version.
I prefer patch v11, where HLogKey does not extend VersionedWritable. Just my
$0.02.

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