Robert Joseph Evans commented on HADOOP-8460:
---------------------------------------------

Roman,

Most of Hadoop's packaging also sets the default up properly, I believe that I saw /var/run...
in the setup scripts too.  It is not a big issue hence it is just a major bug, and we could
drop it to minor if you want.  There is still a potential security hole if you are installing
from the TGZ, and it is good to warn users about it so they don't misconfigure it themselves.
 If you want me to change the text of the warning accordingly, I am happy to do so.

Aaron,

Thanks for the feedback I will update the patches.

> We should document that in a properly setup cluster HADOOP_PID_DIR and HADOOP_SECURE_DN_PID_DIR
should not point to /tmp, but should point to a directory that normal users do not have access
to.
