Subject [jira] [Commented] (YARN-3040) [Data Model] Make putEntities operation be aware of the app's context
Date Wed, 25 Mar 2015 20:43:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-3040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14380731#comment-14380731
] 

Zhijie Shen commented on YARN-3040:
-----------------------------------

bq.  if cluster-id is set, and if not, generate one like cluster-<rm-start-timestamp>
without having a default value per se?

I originally propose this way, but it turns out to be difficult to coordinate <rm-start-timestamp>
among multiple RMs and over RM restarting. IAC, let's file a separate Jira to continue the
discussion of default cluster ID for RM HA: YARN-3399.

> Per design in YARN-2928, implement client-side API for handling *flows*. Frameworks should
be able to define and pass in all attributes of flows and flow runs to YARN, and they should
be passed into ATS writers.
> YARN tags were discussed as a way to handle this piece of information.
