Failed to start service via Cloudera manager, Error displays command timed out


Hi Team,


I am unable to start the services in the hadoop cluster. It displays error message as below:

Command timed-out after 150 seconds

 Cloudera-scm-agent cloudera-scm-server, cloudera-scm-db all are running on the server. In the CM the services aren't starting although.


I am guessing issuemight lie in Cloudera Agent log as Cloudera Manager console is accessible.

Please look into the below mentioned logs and assist:
