Does "stop cluster" in Cloudera Manager do a HBase Graceful Shutdown ?

Does "stop cluster" in Cloudera Manager do a HBase Graceful Shutdown ?

Rising Star

Hi guys

 

I am using CDH 5.6.0 - starving developers version - managed by Cloudera Manager. When we start/stop or restart the cluster through CM, then does HBase do a Graceful Shutdown ?  For now to play safe I first do a HBase Graceful Shutdown and stop the cluster and start it. 

 

And I am assuming that the Cloudera services with have specific "graceful shutdown" equivalent APIs

The service/commands/stop endpoint [1] for HBase service is a greceful shutdown

 

# curl -u 'username:password' -X POST -H "Content-Type:application/json" 'http://CM-SERVER:7180/api/v11/clusters/_REPLACE_WITH_CLUSTERN_NAME/services/_REPLACE_WITH_HASE_SERVICE_NAME/commands/stop'

Thanks Michalis for the clarification.

Of course :-) I have always shouted out loud that I love the Cloudera distribution the best and the open source community is super awesomely responsive and put community version of CDH successfully in production in two placed I have worked :-) and always keep my clusters upto date within weeks of new version announcement....and I have a 3 node CDH cluster at home under my desk for my data crunching I do for my not-for-profit www.medicalsidefx.org !
