[jira] Created: (HADOOP-2373) Name node silently changes state

Name node silently changes state
--------------------------------

                 Key: HADOOP-2373
                 URL: https://issues.apache.org/jira/browse/HADOOP-2373
             Project: Hadoop
          Issue Type: Bug
    Affects Versions: 0.16.0
            Reporter: Robert Chansler
            Assignee: Konstantin Shvachko


1. The name node should create a log message when entering the "extension" period of safe mode after achieving the minimal replication threshold.

Logging state changes is a Good Idea. When diagnosing 2159, there is no evidence whether the name node is in the extension period or not.

2. When in safe mode, the name node should periodically explain _why_ it is still in safe mode. (2159 again)
