Subject [jira] [Commented] (YARN-1390) Add applicationSource to ApplicationSubmissionContext and RMApp
Date Fri, 08 Nov 2013 18:14:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-1390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13817535#comment-13817535

Vinod Kumar Vavilapalli commented on YARN-1390:
-----------------------------------------------

Don't see the point of multiple appTypes.

A Pig query is a pig query and jobs spawned for a Pig query should be of type Pig. I think
the problem is that MR hardcodes the app-type. If we change that to be pluggable, then it
should be enough for you?

Please change the title to reflect your requirement and not the solution. Tx.

> 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.
