-----------------------------

             Summary: TestByteRangeInputStream.testPropagatedClose fails and throw NPE on branch-2
                 Key: HDFS-7049
                 URL: https://issues.apache.org/jira/browse/HDFS-7049
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Juan Yu
            Priority: Minor


On branch-2, TestByteRangeInputStream.testPropagatedClose throw NPE when HftpFileSystem$RangeHeaderUrlOpener.connect
This is due to fix of HDFS-6143 "WebHdfsFileSystem open should throw FileNotFoundException for non-existing paths"
public ByteRangeInputStream(URLOpener o, URLOpener r) throws IOException {
    this.originalURL = o;
    this.resolvedURL = r;
    getInputStream();
  }
the getInputStream() will be called in constructor now to verify if file exists.
Since we just try to test if ByteRangeInputStream#close is called at proper time, we could mock(ByteRangeInputStream.class, CALLS_REAL_METHODS) for testing to avoid the NPE issue.
I believe the trunk version already does this, we just need to merge the test from trunk.
