> HBASE-11520 introduced a subtle change in the configuration, it's release note says
> bq. Remove "hbase.bucketcache.percentage.in.combinedcache". Simplifies config of block cache. If you are using this config., after this patch goes in, it will be ignored. The L1 LruBlockCache will be whatever hfile.block.cache.size is set to and the L2 BucketCache will be whatever hbase.bucketcache.size is set to.
