Subject [jira] [Updated] (YARN-4356) ensure the timeline service v.2 is disabled cleanly and has no impact when it's turned off
Date Fri, 04 Dec 2015 05:03:11 GMT

     [ https://issues.apache.org/jira/browse/YARN-4356?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sangjin Lee updated YARN-4356:
------------------------------
    Attachment: YARN-4356-feature-YARN-2928.poc.001.patch

I'm posting a POC patch to get early feedback.

I haven't added a config that checks the version of the timeline service yet, and I need to
sort out various configuration parameters a little more.

But assuming those things will be in place later on, please take a look at whether the timeline
service v.2 code/memory/behavior is cleanly turned off if the timeline service v.2 is disabled.
I would greatly appreciate your feedback. Thanks!

> For us to be able to merge the first milestone drop to trunk, we want to ensure that
once disabled the timeline service v.2 has no impact from the server side to the client side.
If the timeline service is not enabled, no action should be done. If v.1 is enabled but not
v.2, v.1 should behave the same as it does before the merge.
