Haijun Cao commented on HBASE-1634:
-----------------------------------
Stack,
Just so you know, I am able to reproduce again. It happens while doing
sequentialWrite 100x1m records, this time, master/region servers did not crash
(so the crash log I mentioned in the earlier comment may be misleading).
sequentialWrite are still successful, just UI not working. I applied the
purgewrongfamily script and NPE is gone.
I am going to run the test again with DEBUG mode, will email you the log if I
am able to reproduce.

> I have a .META. from bryan duxbury that has a row with only historian data.
> List does whole row, not just info, so if only historian entries, a row is
> returned. We then try and get a regioninfo from this row and NPE.
> As to why this happens, jd suggests that since we moved to async historian
> updates, row may have been deleted already. Confirm.
