getResourceAsStream
                 Key: ZEPPELIN-6268
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-6268

          Issue Type: Bug
            Reporter: ChoiByungHo
            Assignee: ChoiByungHo


  Problem

  - FileInputStream not properly closed in AlluxioInterpreterTest
  - Missing null checks for getResourceAsStream() calls that can return null
  - Potential NullPointerException in multiple interpreter classes

  Solution

  - Add try-finally block to ensure FileInputStream is closed
  - Add null checks after getResourceAsStream() calls
  - Throw appropriate exceptions with clear error messages
