> HBASE-11520 improved configuration of bucket cache to no longer require {{hbase.bucketcache.percentage.in.combinedcache}}.
This was done rather aggressively, with this previously mandatory configuration being ignored.
This can result in RS crashes for unsuspecting users. We should add a WARN when {{hbase.bucketcache.percentage.in.combinedcache}}
is set to make debugging the crash more straight forward.
