Hi,

I have installed Cloudera 5.7.1 using CentOS 7. Issue is that resource manager is not starting in YARN MR2.

Error is permission denied, below is the snippet from stderr.log file.

At present supervisor.conf file is being created as root user with read permission only to root, that might be the reason, however, i am not sure why would that be the case.

Please help.
