[~xucang], The addendum patch hasn't landed in branch-1 & branch-1.4 though the
original patch is present in those 2 branches. Could you please get them in? :)

Sean Busbey commented on HBASE-20917:
-
sorry for not updating. the 2.0.4 patch already landed, so you should be good
to go. this is open still for the branch-2.1 backport, which is blocked on
HBASE-19722. I think no rush on that one; can wait for the next 2.1 release.

This is also missing from branch-2.0 and it looks like the same problem is
there. [~stack] unless I hear otherwise from you I'm going to push the same
patch there that I send to branch-2.1.

Ted Yu commented on HBASE-20917:
bq. is there anything to stop requestsMap being set to null after the check but
before the use?
As far as I can tell, requestsMap is private. I only found one assignment to
this field in the start() method. Meaning after the field is assigned, it
wouldn't be set to null.
As to why the null check is needed, see the following from description:
bq. requestsMap is only initialized for the meta region.
bq. It doesn't look like its committed yet.
Let me know if I should merge the fix to 2.0 branch or you're going to merge
the fix yourself.
thanks

[~yuzhih...@gmail.com] You are right, I checked other code, tableName can be
compared directly. Using #getName() was unnecessary. Thanks for your fix! +1

Ted Yu commented on HBASE-20917:
[~xucang]:
If read your code correctly, {{start}} method checks hbase:meta table. Since
TableName can be compared directly, I simplified the code a little bit in patch
v2.
Can you take a look ?
thanks
