Job Tracker is not starting

Hi All,

When I enabled security trying to start the job tracker daemon is not
starting up I see the error pasted below

I have added all the user and groups in my mapred-queue-acls.xml

mapred/tmp/system is owned by mapred

but cloudera is not (hdfs hadoop)

drwxrwxrwx 10 mapred mapred 4096 Jan  7 16:12 ..
drwxrwxrwx  2 mapred mapred 4096 Jan  7 16:12 system
drwxrwxrwx  4 mapred mapred 4096 Jan  7 16:12 .
