It's a minor bug in test case. `val testDir = null` will keep be `null` as it's immutable, so in finally block, nothing will be cleaned. Another `testDir` variable created in try block is only visible in try block. ## How was this patch tested? Run existing test case and passed. Author: mwws <wei.mao@intel.com> Closes #12999 from mwws/SPARK_MINOR. |
