Cloudera Agent won't start - WARNING Stopping daemon

Adr — Wed, 01 Feb 2017 13:54:44 GMT

Hello,

I tried to migrate Cloudera from 5.9 to 5.10. Cloudera Manager Server works well but the agent on the same server doesn't want to start.

The cloudera-scm-agent.log shows only this :

I did'nt find any other helpful logs.

How can I get more info about this ?

Thanks

It was maybe a corruption in the /var/run folder.

I deleted it and the agent recreated it. Now it works.
