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, 11 Nov 2013 11:01:22 GMT

    [ https://issues.apache.org/jira/browse/YARN-1390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13818866#comment-13818866
] 

Hitesh Shah commented on YARN-1390:
-----------------------------------

To add to the above comment, from a YARN point of view, an application is just an application.
It has a defined type which can be used eventually to apply some logic or enforce rules (
for example, which history server to redirect to or which history plugin to apply ). The same
application i.e same framework or same type of application when used in different contexts
by definition should not have different types.

> 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.
