stack commented on HBASE-1020:
------------------------------
Can just dump current metrics to log; has region count, and store file count.
Memcache metric has size, not item count (Might be possible to add this as
metric -- I think we keep it.. not so for store files).
> Regionserver OOME handler should dump vital stats
