[jira] [Created] (HIVE-8458) Potential null dereference in Utilities#clearWork()

Ted Yu created HIVE-8458:
----------------------------

             Summary: Potential null dereference in Utilities#clearWork()
                 Key: HIVE-8458
                 URL: https://issues.apache.org/jira/browse/HIVE-8458
             Project: Hive
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
    Path mapPath = getPlanPath(conf, MAP_PLAN_NAME);
    Path reducePath = getPlanPath(conf, REDUCE_PLAN_NAME);

    // if the plan path hasn't been initialized just return, nothing to clean.
    if (mapPath == null && reducePath == null) {
      return;
    }

    try {
      FileSystem fs = mapPath.getFileSystem(conf);
{code}
If mapPath is null but reducePath is not null, getFileSystem() call would produce NPE
