             Summary: Resource Leak due to Files.walk
                 Key: YARN-10976
                 URL: https://issues.apache.org/jira/browse/YARN-10976
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: lujie


Stream creates by File.walk should be closed, like jdk said:
 * <p> The returned stream encapsulates one or more \{@link DirectoryStream}s.
 * If timely disposal of file system resources is required, the
 * {@code try}-with-resources construct should be used to ensure that the
 * stream's \{@link Stream#close close} method is invoked after the stream
 * operations are completed. Operating on a closed stream will result in an
 * {@link java.lang.IllegalStateException}.
