Subject [jira] Updated: (HBASE-2509) NPEs in various places, HRegion.get, HRS.close

stack updated HBASE-2509:

    Attachment: hbase-2509-v3.patch

Here's Ryan's patch with a unit test. Condition is kinda hard to manufacture. I had to kinda
force it by artificially setting closing flag on region and then adding new threads.... rather
than do a straight close.   But I get a NPE so for sure its possible.

> The root cause is a delayed init of the RegionScanner.storeHeap means it can be null,
not all accessors of it (specifically in close()) checked for that.
