Jonathan Gray commented on HBASE-1615:
--------------------------------------
Issue is, we have a local readBlock in CompactionReader but that the delegate
Reader does not use our cacheBlock method.
I think this might be much easier if we just upgrade "block should be cached"
to a passed boolean to HFile Reader and Scanner instantation, rather than all
this subclassing, delegating, and such.
