-------------------------------------
Summary: Support fast and graceful master failover
Key: HBASE-6960
URL: https://issues.apache.org/jira/browse/HBASE-6960
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.94.2, 0.96.0
Reporter: Jonathan Hsieh
If you have multiple masters, you should be able to kill the primary and have
the backups assume control within seconds instead of having to wait the default
3mins before an ephemeral znode expires.
The expected behavior is similar to how region servers when killed (not -9)
trigger the servers shutdown handler and quickly pass of its regions for
reassignment. In this case, a master that is killed is removes the znode and
allow another to become the primary. A related follow on feature could be the
ability to failover to another primary without taking the orignal primary down.
