Subject [jira] Commented: (HBASE-2465) HMaster should not contact each RS on startup
Date Tue, 20 Apr 2010 21:07:51 GMT

stack commented on HBASE-2465:
------------------------------

This was a failover of the master case?  It was not a fresh start?  Only on failvover do we
do the contact of all regionservers.

> On startup, in verifyClusterState, the master contacts each region server serially. If
a region server is down it will retry for several minutes (if the client retry setting is
high). During this period, the master cannot be shut down, and also isn't processing real
work.
