[jira] [Created] (HADOOP-9545) Improve logging in ActiveStandbyElector

Todd Lipcon created HADOOP-9545:
-----------------------------------

             Summary: Improve logging in ActiveStandbyElector
                 Key: HADOOP-9545
                 URL: https://issues.apache.org/jira/browse/HADOOP-9545
             Project: Hadoop Common
          Issue Type: Improvement
          Components: auto-failover, ha
    Affects Versions: 2.0.5-beta
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor


The ActiveStandbyElector currently logs a lot of stuff at DEBUG level which would be useful for troubleshooting. We've seen one instance in the wild of a ZKFC thinking it should be in standby state when in fact it won the election, but the logging is insufficient to understand why. I'd like to bump most of the existing DEBUG logs to INFO and add some additional logs as well.
