> BC's hbase.bucketcache.ioengine by default is empty now. Means now BC.
> Make this default to be 'offheap'.  And the default off heap size for the BC also to be provided. This can be 8 GB?  Better to make it also a % of the Xmx. Lets continue to be 40% of Xmx as LRU cache default size.
> When user has to disable BC, configure size as 0. An empty value of this config will be treated as default size.
