Milind Bhandarkar commented on HDFS-1113:
-----------------------------------------

Owen, that is an interesting way to abuse. However,HDFS has namenode audit log that logs this
chown.

> owner and group of a file/directory, and namespace/diskspace quota for a directory are
mutable attributes. If I have writable access to a directory, say /team/MyTeam, and if there
are subdirectories underneath, such as /team/MyTeam/TeamMember1, /team/MyTeam/TeamMember2,
then I should be able to chown, chgrp, setQuota, clrQuota on TeamMemeber{1|2} subdirectories.
Currently in HDFS (and in Posix), it requires me to be a superuser to perform these operations.
