Description
It is currently not possible to configure the privacy of task attempt log directories (FsPermission is hardcoded to 700). This behavior is not currently configurable and is not consistent with other services' log files in the Hadoop ecosystem.
See below. 'userlogs' directory is readable by 'other', but not 'job_*' directory
-bash-4.1$ ls -lah /var/log/hadoop-0.20-mapreduce/userlogs/ | head -n7
