> \# Uncomment below if you intend to use off heap cache. For example, to 
> allocate 8G of 
> \# offheap, set the value to "8G".
> \# export HBASE_OFFHEAPSIZE=1G
> {quote}
> This is what we have in hbase-env.sh now. We need more notes around this and 
> some suggestion. May be more details in book also. This depends on whether we 
> want L2 off heap BC as the default data cache in 2.0. (I would like to and 
> will open a jira soon) Also if users use off heap MSLAB pool, then that also 
> to be added up.. 
> As of now we will use a ByteBufferPool which pool direct BBs and this is ON 
> by default. The max size, this pool can keep is 2 MB *  2 * #handlers.
> Will add more details as we turn ON other features.
