Subject [jira] [Commented] (YARN-2900) Application (Attempt and Container) Not Found in AHS results in Internal Server Error (500)
Date Mon, 08 Dec 2014 23:01:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14238619#comment-14238619

Zhijie Shen commented on YARN-2900:

bq.  I am not sure why the timelineserver throws some exception and we get a NotFound on the
browser. Can you explain what was the test that you did here?

What i did:

1. Start the timeline server while system metrics publisher is enabled for RM.
2. Submit a MR example job.
3. Type {{http://localhost:8188/ws/v1/applicationhistory/apps/application_1417818619773_0001?user.name=zshen}}
in browser, and check the output, which is right.
4. Type {{http://localhost:8188/ws/v1/applicationhistory/apps/application_1417818619773_0002?user.name=zshen}},
and look for NOT_FOUND message. However no response at all. And I see the aforementioned exception
in the timeline server log.

I applied this patch on trunk, and I could reproduce this issue. Undoing this patch, {{http://localhost:8188/ws/v1/applicationhistory/apps/application_1417818619773_0002?user.name=zshen}}
will return Internal Server Error (500), which is the expected current behavior. Did you have
a chance to reproduce it at ur side?
