Namenode in Safemode reports to Simon non-zero number of deleted files during startup
-------------------------------------------------------------------------------------

                 Key: HADOOP-1495
                 URL: https://issues.apache.org/jira/browse/HADOOP-1495
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.13.0
            Reporter: Hairong Kuang
             Fix For: 0.14.0


Currently when a namenode starts up it may call "delete" when loading edits. But metrics file_deleted
is collected and reported in FSDirectory where it does not and is not able to check if namenode
is in safemode. So from the monitoring UI, we see non-zero number of files deleted.

A possible fix is to have delete to return the number of files deleted and then the metrics
is collected and reported at NameNode the same as other namenode metrics.
