Jean-Daniel Cryans commented on HBASE-6533:
-------------------------------------------
Currently those two features are just incompatible, you use one or the other.
Maybe we should add a check in HBaseConfiguration to make sure both aren't
enabled, no need to throw the exception that deep in the code (and you'd have
to do it inside WAL compression for replication too).
In any case the real fix is described in HBASE-5778, the rest is just hacks.
