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  for HBase service is a greceful shutdown

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 !
