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.
