stack commented on HBASE-7390:
------------------------------
[~nkeywal] I follow you now. Yes, we can miss events and yes the master deals
(and yes no harm in improving doc).
IIRC (I believe I added SPLIT), we tickle in case the transition to SPLIT from
SPLITTING is missed by the master. We keep tickling till master acknowledges
the SPLIT message (by removing SPLIT znode -- haven't looked at code).
> Add extra test cases for assignement on the region server and fix the related
> issues
