stack commented on HBASE-19165:

Test failure is a good one. I filed HBASE-19165 to address it later. The test failure is part
of a larger issue of what to do when empty state (Can have empty state as part of migration
but HBASE-19193 shows we can have an empty state if Master crashes in midst of a Table delete......Good

> 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:

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.
