> ResourceLocalizationService.testPublicResourceInitializesLocalDir fails Intermittently
due to IOException from cleanup. The stack trace is the following from test report at
> https://builds.apache.org/job/PreCommit-YARN-Build/7729/testReport/org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer/TestResourceLocalizationService/testPublicResourceInitializesLocalDir/
> {code}
> Error Message
> Unable to delete directory target/org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.TestResourceLocalizationService/2/filecache.
> Stacktrace
> java.io.IOException: Unable to delete directory target/org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.TestResourceLocalizationService/2/filecache.

> {code}
> It looks like we can safely ignore the IOException in cleanup which is called after test.
> The IOException may be due to the test machine environment because TestResourceLocalizationService/2/filecache
is created by ResourceLocalizationService#initializeLocalDir.
> testPublicResourceInitializesLocalDir created 0/filecache, 1/filecache, 2/filecache and
3/filecache
> {code}
>     for (int i = 0; i < 4; ++i) {
>       localDirs.add(lfs.makeQualified(new Path(basedir, i + "")));
>       sDirs[i] = localDirs.get(i).toString();
>     }
> {code}
