Yongjun Zhang created HDFS-8596:
-----------------------------------

             Summary: HDFS-8572 breaks TestDistributedFileSystem et al tests in branch-2
                 Key: HDFS-8596
                 URL: https://issues.apache.org/jira/browse/HDFS-8596
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: HDFS
    Affects Versions: 2.7.1
            Reporter: Yongjun Zhang
            Assignee: Yongjun Zhang


After HDFS-8572, some tests failed in branch-2 as below:
{code}
Running org.apache.hadoop.hdfs.TestDistributedFileSystem
Tests run: 17, Failures: 0, Errors: 3, Skipped: 0, Time elapsed: 44.302 sec <<< FAILURE!

sec  <<< ERROR!

        at org.apache.hadoop.hdfs.TestDistributedFileSystem.testAllWithDualPort(TestDistributedFileSystem.java:683)
{code}

I found that the cause is the wrong setting of "datanode" attribute in ServletContext introduced
by this change.
