Security for 0.22

Hi All ,


As I understand , there is some security code in 22, but some patches are
not there . This includes MR-LinuxTaskController and SPNego support for the
WebUI.
I am trying to missing features/patches and best approach for incorporating
 security in 0.22. Please let me know your thoughts and recommendations for
this.

Thanks and Regards,
Benoy Antony

0.22 has had the linux task controller removed, because it lacks a
forward port of MAPREDUCE-2178. (MR-2178 fixes a root exploit in the
linux task controller.) That means that all 0.22 Hadoop clusters run
all mapreduce tasks as the same uid as the task tracker.
