[Vanilla] pid files in /tmp

[Andrew Lazarev]

Vanilla plugin stores .pid files in the /tmp folder. It is better to put them to /var/run. Or at least group in subdir.

ubuntu@al-test6-master-001:~$ ls -la /tmp/*.pid
-rw-rw-r-- 1 hadoop hadoop 5 Sep 22 20:47 /tmp/hadoop-hadoop-namenode.pid
-rw-rw-r-- 1 hadoop hadoop 5 Sep 22 20:47 /tmp/mapred-hadoop-historyserver.pid
-rw-rw-r-- 1 hadoop hadoop 5 Sep 22 20:47 /tmp/yarn-hadoop-resourcemanager.pid
