Ravi Phulari commented on HADOOP-5942:
--------------------------------------
Safe mode is a Namenode state in which it does not accept changes to the name
space (read-only) .
http://hadoop.apache.org/core/docs/r0.20.0/commands_manual.html#dfsadmin
But when namenode is entered in safemode manually , Chown ,chgrp , chmod
operations are allowed which makes changes in namespace and edit logs .
> Chown , chgrp , chmod operations allowed when namenode is in safemode .
