Anoop Sam John commented on HBASE-11696:
----------------------------------------
bq.Nice. Where is this doc'd. This feature is not on by default, right (because
afraid messing w/ mem settings will mess up GC?). Shouldn't we turn it on in
master branch?
Will add to our book. Will work on doc patch. Yes I will raise an issue to
turn it ON by default. Will do some more long run testing around this before
we tunr it ON.
bq.You want this delineation for ergonomic feature?
Was just thinking whether it will help. Will have to read through that code
more and test. I believe you work in this area. So can help you boss.
> Make CombinedBlockCache resizable.

> HBASE-5349 adds auto tuning of memstore heap and block cache heap. Block
> cache needs to be resizable in order for this. CombinedBlockCache is not
> marked resizable now. We can make this. On resize the L1 cache (ie. LRU
> cache) can get resized.
