Anoop Sam John commented on HBASE-19165:
----------------------------------------

Can the state cell be there with empty value?  You also say this is not possible ideally and
if that means some issue?  Correct me if am wrong.  May be specific handling can be there.
 Ya agree on return as null and handle in using places.

> A few of us trying migration from hbase1 to hbase2 have run into various assignment issues.
In my case, I see that Master coming online, reading hbase:meta, finding an issue in OPENING
state and then just not assigning. My thought is that its expecting a callback to come in.
Eventually log is fills with this sort of stuff:
> 2017-11-02 15:02:54,237 WARN  [ProcExecTimeout] assignment.AssignmentManager: TODO Handle
stuck in transition: rit=OPENING, location=ve0528.halxg.cloudera.com,16020,1509657692581,
table=IntegrationTestBigLinkedList, region=919cc6636ffbed17f628f335d3a58726
> Let me get a cleaner run. This current log is polluted by a few restarts.
