stack commented on HBASE-19074:
-------------------------------
Ditto in WALObserver, I made the Deprecated for now.
{code}
/**
* Called before a {@link WALEdit}
* is writen to WAL.
*
* @return true if default behavior should be bypassed, false otherwise
* @deprecated Since hbase-2.0.0. To be replaced with an alternative that
does not expose
* InterfaceAudience classes such as WALKey and WALEdit. Will be removed in
hbase-3.0.0.
*/
// TODO: return value is not used
@Deprecated
default boolean preWALWrite(ObserverContext<? extends
WALCoprocessorEnvironment> ctx,
RegionInfo info, WALKey logKey, WALEdit logEdit) throws IOException {
return false;

> Going through Observers after fixing up MasterObserver, i see a few
> violations such as Store returning a MemStoreSize instance (which would let
> coprocessors inc/dec MemStore size which would mess us up). This issue is
> about cleaning these remainders up.
