stack commented on HBASE-19452:
-------------------------------
Moved it out to 2.0.0 -- our general bucket of 2.0.0 issues that we'll have to
sort through one of these days to figure 2.1 and 3.0.0 -- after discussion w/
[~ram_krish] and [~anoop.hbase]; we need more time than is available readying
this for hbase-2 (and it has to be right if we don't want to piss of our
users). Thanks lads.

> 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.
