Reduce verbosity when double-closing edit logs
----------------------------------------------
Key: HDFS-2675
URL: https://issues.apache.org/jira/browse/HDFS-2675
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
Currently the edit logs log at WARN level when they're double-closed. But this
happens in the normal flow of things, so we may as well reduce it to DEBUG to
reduce log spam in unit tests, etc.
