Appy commented on HBASE-17582:
------------------------------
definitely an oversight. :(
Don't know about StoreFileWriter though. It says in implementation
{noformat}
public Builder withShouldDropCacheBehind(boolean shouldDropCacheBehind/*NOT
USED!!*/) {
// TODO: HAS NO EFFECT!!! FIX!!
return this;
}
{noformat}
Which seem to have been added as note in HBASE-15118.
