--------------------------------------
Summary: Not running balancer because processing dead
regionservers, but empty rs list, and state does not recover
Key: HBASE-21266
URL: https://issues.apache.org/jira/browse/HBASE-21266
Project: HBase
Issue Type: Bug
Affects Versions: 1.4.8
Reporter: Andrew Purtell
Fix For: 1.5.0, 1.4.9
Found during ITBLL testing. AM in master gets into a state where manual
attempts from the shell to run the balancer always return false and this is
printed in the master log:
2018-10-03 19:17:14,892 DEBUG
[RpcServer.default.FPBQ.Fifo.handler=21,queue=0,port=8100] master.HMaster: Not
running balancer because processing dead regionserver(s):
Note the empty list.
This errant state did not recover without intervention by way of master
restart, but the test environment was chaotic so needs investigation.
