Subject [jira] [Created] (YARN-4552) NM ResourceLocalizationService should check and initialize local filecache dir (and log dir) even if NM recover is enabled.

Junping Du created YARN-4552:
--------------------------------

             Summary: NM ResourceLocalizationService should check and initialize local filecache
dir (and log dir) even if NM recover is enabled.
                 Key: YARN-4552
                 URL: https://issues.apache.org/jira/browse/YARN-4552
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Junping Du
            Assignee: Junping Du
            Priority: Critical


In some cases, user are cleanup localized file cache for debugging/trouble shooting purpose
during NM down time. However, after bring back NM (with recovery enabled), the job submission
could be failed for exception like below:
{noformat}
Diagnostics: java.io.FileNotFoundException: File /disk/12/yarn/local/filecache does not exist.
{noformat}
This is due to we only create filecache dir when recover is not enabled during ResourceLocalizationService
get initialized/started.
