Rishit Shroff commented on HBASE-12753:
---------------------------------------
The histograms removed from QuorumAgent were of no use or can be added back
later?
bq. yes, or use any existing one from the current trunk.
You remove AbstractWAL but was this the only place it was used?
bq. well it was used in HBase codebase of our internal hydrabase branch. Since,
we are not merging those pieces directly (as those are not isolated) there is
no other use of AbstractWAL in the hbase-consensus module.
Thanks,
Rishit

> The HydraBase codebase abstracted out WAL into :
> 1) HBase WAL (HLog)
> 2) Quorum WAL
> In order to make the application independent, AbstractWAL was used to make it
> transparent from HRegionServer perspective.
> In the trunk, there is a similar interface WALProvider. Hence, removing the
> AbstractWAL from the hbase-consensus code base.
