      Description

      There are a few places in HDFS code that are closing an output stream with IOUtils.cleanupWithLogger like this:

        try {
          ...write to outStream...
        } finally {
          IOUtils.cleanupWithLogger(LOG, outStream);
        }
      

      This suppresses any IOException that occurs during the close() method which could lead to partial/corrupted output without throwing a corresponding exception. The code should either use try-with-resources or explicitly close the stream within the try block so the exception thrown during close() is properly propagated as exceptions during write operations are.
