------------------------------------

             Summary: WARN if hbase.bucketcache.percentage.in.combinedcache is 
set
                 Key: HBASE-13821
                 URL: https://issues.apache.org/jira/browse/HBASE-13821
             Project: HBase
          Issue Type: Bug
          Components: regionserver, Usability
    Affects Versions: 1.1.0, 1.0.0, 2.0.0, 1.2.0
            Reporter: Nick Dimiduk
            Priority: Minor


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.
