Anoop Sam John commented on HBASE-12095:
----------------------------------------
It is strange to use SecureProtobufLogWriter when encryption is marked as
disabled. SecureProtobufLogReader usage make sense.
IMO we should see what all combinations should be supported or even simplifying
the usage for WAL encryption.
[~ashish singhi] Configuring SecureWALCellCodec explicitly along with above 3
configs , still you will see this issue?
> SecureWALCellCodec should handle the case where encryption is disabled
