> This is a 2.0 only issue and induced by HBASE-16407.
> We are initializing MSLAB chunk pool along with RS start itself now. (To pass
> it as a HeapMemoryTuneObserver).
> When MSLAB is turned off (ie. hbase.hregion.memstore.mslab.enabled is
> configured false) we should not be initializing MSLAB chunk pool at all. By
> default the initial chunk count to be created will be 0 only. Still better
> to avoid.
