Subject [jira] [Commented] (YARN-4207) Add a non-judgemental YARN app completion status
Date Tue, 13 Oct 2015 17:40:05 GMT

Siddharth Seth commented on YARN-4207:
--------------------------------------

[~rhaase] - thanks for taking this up.
Along with the change to FinalApplicationStatus, a change is also required to the proto definition
(yarn_protos.proto). There'll be a set of converter methods which translate between the proto
and FinalApplicationStatus which will also need to be changed.

Other than that, I believe adding this additional value is a safe change.

> For certain applications, it doesn't make sense to have SUCCEEDED or FAILED end state.
For example, Tez sessions may include multiple DAGs, some of which have succeeded and some
have failed; there's no clear status for the session both logically and from user perspective
(users are confused either way). 
> There needs to be a status not implying success or failure, such as "done"/"ended"/"finished".
