Andrew Purtell commented on HBASE-1124:
---------------------------------------
In some tests, I observed that master did not respond in time to a heartbeat
from the HRS carrying META, so it would reinitialize. Master would then try to
update META from ProcessRegionOpen but update would fail (processBatchOfRows
complains about HRS assigned to META not accepting writes). Observed warnings
about META being partially offline. This was a terminal state.

> Balancer kicks in before all regions are assigned out. Causes confusion.
> Master won't accept OPENs from "overloaded" HRS. Master is slow to respond to
> UI and HRS during. Master sometimes takes too long to respond to a HRS
> heartbeat and so the HRS will reinit. This causes more confusion.
