Subject [jira] [Commented] (YARN-1390) Provide a way to capture source of an application to be queried through REST or Java Client APIs
Date Mon, 02 Dec 2013 17:48:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-1390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836723#comment-13836723
] 

Alejandro Abdelnur commented on YARN-1390:
------------------------------------------

Agree with Steve, we should limit the length of a tag and number of tags. I'd suggest going
hardcoded for now, i.e. 50chars/10tags and going configurable later if the need arises.

> In addition to other fields like application-type (added in YARN-563), it is useful to
have an applicationSource field to track the source of an application. The application source
can be useful in (1) fetching only those applications a user is interested in, (2) potentially
adding source-specific optimizations in the future. 
> Examples of sources are: User-defined project names, Pig, Hive, Oozie, Sqoop etc.
