[jira] [Created] (YARN-8162) Method DirectoryCollection#verifyDirUsingMkdir isn't needed anymore

Yufei Gu created YARN-8162:
------------------------------

             Summary: Method DirectoryCollection#verifyDirUsingMkdir isn't needed anymore
                 Key: YARN-8162
                 URL: https://issues.apache.org/jira/browse/YARN-8162
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.1.0
            Reporter: Yufei Gu
            Assignee: Yufei Gu


First of all, DirectoryCollection#verifyDirUsingMkdir doesn't do what it claims to do, it creates a file but its Java doc says it create a dir. What's more, it is no longer needed after HADOOP-13738 (DiskChecker should perform some disk IO). It duplicates what HADOOP-13738 does. We should remove it.
