Subject [jira] [Commented] (YARN-8734) Readiness check for remote service
Date Fri, 21 Sep 2018 22:18:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16624250#comment-16624250

Gour Saha commented on YARN-8734:
---------------------------------

[~eyang] this is a pretty useful feature so thanks for taking this up. Although I did not
get a chance to test the patch it overall looks okay.

But one question: from a naming perspective, the opposite of remote is local. What does local
service mean? Are we excluding local services? To me, it seems like we wanted to mean external
services instead of remote services. Thoughts?

> 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.
