> 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.
