Reverse order of AssignmentManager and MetaNodeTracker in ZooKeeperWatcher
--------------------------------------------------------------------------
Key: HBASE-3172
URL: https://issues.apache.org/jira/browse/HBASE-3172
Project: HBase
Issue Type: Bug
Components: master, zookeeper
Affects Versions: 0.90.0
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Critical
Fix For: 0.90.0
Over in HBASE-3159, I reported a similar double-opened issue but for META.
This is because of the fact that the META unassigned znode has two different
consumers {{MetaNodeTracker}} in use by the CatalogTracker and
{{AssignmentManager}} which uses it for normal regions-in-transition stuff.
The AssignmentManager needs to go first, otherwise we can get double handling
of state transitions.
