Review request for Ambari, Dmitro Lisnichenko and Mahadev Konar.

Bugs: AMBARI-4354

Repository: ambari


HostCleanup should also check the following directories (and clean):


For example, if the /tmp/hadoop-nagios directory is present, but it doesn't have the right
ownership/perms for nagios user, the Hive Metastore Nagios alert will occur. I saw this after
doing an install on an un-clean machine.

Hive Metastore status
CRIT for about a minute
CRITICAL: Error accessing Hive Metastore status [Error creating temp dir in hadoop.tmp.dir
/tmp/hadoop-nagios due to Permission denied]

An easy way to reproduce this:

1) Perform install
2) Go to Nagios server machine
3) Change perms on /tmp/hadoop-nagios so that the nagios user does not have access
4) The Nagios alert will fire

Tested on 1.3.3
