[jira] [Commented] (YARN-8734) Readiness check for remote service

    [ https://issues.apache.org/jira/browse/YARN-8734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16597710#comment-16597710 ] 

Billie Rinaldi commented on YARN-8734:
--------------------------------------

We might need to check the individual components of the remote service to see if they are in READY state. I think the service can be in state STABLE before all its components are READY – or at least that used to be the case. I can't recall if we've fixed that.

> When a service is deploying, there can be remote service dependency.  It would be nice to describe ZooKeeper as a dependent service, and the service has reached a stable state, then deploy HBase.
