> On trunk we have NameNode which records FilesCreated and FSDirectory records files_deleted.
While NameNode records actual number of files created, FSDirectory records deletion of files
and directories. These are not consistent. It would be good to re-factor these metrics so
that we collect only Inode counts in FSDirectory and file creation/deletion in NameNode.
