Which database are you using ? ...
Check whether SELINUX is disabled too

When using Cloudera Manager, you should start and stop services via the CM
API (by adding a service for your component, etc.) not via the Linux
service commands.

Hi,

May I know how it got resolved. I'm also getting the same for Rundeck Server.

@Gayathri68,

You need to remove the pid file most likely.

You'll need to find out where the pid file is stored.

Use "strace" to see where it is finding the file if you are on a system where strace can be run

Rundeck is no a Cloudera product, though, so you might check here:
