I think in case of other built-in services like HDFS and Yarn, there are some kind of health tests that trigger alerts when any one role goes down. What I want to know is how to implement this feature with a custom service created using CSD framework. I couldn't find anything relevant in the CSD doc: https://github.com/cloudera/cm_ext/wiki ...
