Start/Stop of large cluster untenable
-------------------------------------
Key: HBASE-1583
URL: https://issues.apache.org/jira/browse/HBASE-1583
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.20.0
Starting and stopping a loaded large cluster is way too flakey and takes too
long. This is 0.19.x but same issues apply to TRUNK I'd say.
At pset with our > 100 nodes carrying 6k regions:
+ shutdown takes way too long.... maybe ten minutes or so. We compact regions
inline with shutdown. We should just go down. It doesn't seem like all
regionservers go down everytime either.
+ startup is a mess with our assigning out regions an rebalancing at same time.
By time that the compactions on open run, it can be near an hour before whole
thing settles down and becomes useable
