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 <<<

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