------------------------------
Summary: 2.7 RM app page is broken
Key: YARN-4281
URL: https://issues.apache.org/jira/browse/YARN-4281
Project: Hadoop YARN
Issue Type: Bug
Reporter: Chang Li
Assignee: Chang Li
Fix For: 2.7.2
2.7 RM app page is broken by the cherry pick of YARN-3248 on 23/Sep. It broke
the work around 2.7 patch of YARN-3544 to let it still use container report.
Currently, our cluster's 2.7 RM app page is completely broken due to 500 error,
which is caused by when user UGI is null, completed app can not retrieve its
container report, and in that code path, it doesn't catch
ContainerNotFoundException, but throw the exception, therefore cause the 500
error.
Running app is also broken because of the way it construct containerID by
{code} "ContainerId.newContainerId(
appAttemptReport.getApplicationAttemptId(), 1)"
{code},
which will not include epoch number, so it will also get
ContainerNotFoundException and throw 500 error.
But right now we can use the branch 2 patch for YARN-3544, instead of the work
around 2.7 patch because branch 2 patch on 2.7 is no longer blocked.
