Storm Lee commented on HBASE-5578:
----------------------------------
I meet it only once, may not reproduce easily. My Hbase cluster has 9 RSes,
only one crushed. It is fresh start up , nothing under /hbase. And than I use a
tool to put data all the time(use HTable.put()). This RS runs about 45 hours
already when the NPE happened. The compaction and split also continued all the
time.
> NPE when regionserver reported server load, caused rs stop.
