---------------------------------

Thanks for working this. [~zjshen].
The patch looks good over.
One comment: Can we do the same thing for getAppAttempts and getContainers ?

> 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.
