Since we have no idea how you have changed your cluster or permissions, our
straight advice would
be to re-install and get it back to a state that we can actually support.
But, if you want to go spelunking -

Look in /export/rocks/install/rocks-dist/....../build/nodes.
Then look at the code snippets between <eval> tags.  When a node's kickstart
file is generated
things inside <eval> tags are run on the frontend.   You will see things
like cat <path-to-some-file> or
echo.   Anything in the <eval> is run as user apache.
