Subject [jira] [Commented] (YARN-2900) Application Not Found in AHS throws Internal Server Error with NPE
Date Mon, 24 Nov 2014 22:44:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14223691#comment-14223691
] 

Zhijie Shen commented on YARN-2900:
-----------------------------------

bq. Issue is spacing in the config file. Here is the updated stack trace.

Then, this log message was expected when the app is not found. But INTERNAL_SERVER_ERROR is
bad. We should return NOT_FOUND instead. We can capture XXXXNotFoundException and convert
it to webapp.NotFoundException.
