Allen Wittenauer commented on HADOOP-6606:
------------------------------------------

Your Linux FHS docs bounce off of me, given I run Solaris. :)

This looks a lot like an OS specific fix that already has a tunable in place that could be changed at install time.  In fact, for Cloudera, it would seem to be smarter to specifically make that happen at RPM install time rather than burden the Hadoop base with a dir that will ultimately need special permissions.

> /tmp should not be used as a pid directory. There is too high a likelihood that pid files could be altered or deleted. A more reasonable default is $HADOOP_HOME/pids.
