Zhijie Shen updated YARN-3701:
------------------------------
    Attachment: YARN-3701.1.patch

Create a patch to swallow the exception on generating the individual app report. In addition,
fix another problem in this patch too: getting rid of doing access check multiple times when
generating an app report and getting AM container.

> Nowadays, if some error of generating a single app report when getting the application
list from generic history service, it will throw the exception. Therefore, even if it just
1 out of 100 apps has something wrong, the whole app list is screwed. The worst impact is
making the default page (app list) of GHS web UI crash, wile REST API /applicationhistory/apps
will also break.
