Stop and starting roles using commandline in Kafka backend

[#1]

Does anyone here can share if we can perform stop and start of roles using commandline in Kafka backend if the Cloudera Manager is down?

Hello @Syl1234 

Thank you for reaching out Cloudera Community.

We can start/stop the service using supervisord on the host level where the cluster roles deployed, however it will cause role/service status discrepancy in the CM's backend database.  Hence it is always recommended to stopping and restarting cluster services should perform through Cloudera Manager only.   Kindly refer our product documentation [0]

If you are looking for cli options, You can make use of the REST API call /clusters/{clusterName}/services/{serviceName}/roleCommands/stop under CM UI -> Support -> API Explorer or API Documentation.
