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

             Summary: TestFSHDFSUtils assumes wrong default port for Hadoop 
3.0.1+
                 Key: HBASE-19963
                 URL: https://issues.apache.org/jira/browse/HBASE-19963
             Project: HBase
          Issue Type: Task
          Components: test
            Reporter: Mike Drob


We try to accommodate HDFS changing ports when testing if it is the same FS in 
our tests:
https://github.com/apache/hbase/blob/master/hbase-server/src/test/java/org/apache/hadoop/hbase/util/TestFSHDFSUtils.java#L156-L162

{code}
    if (isHadoop3) {
      // Hadoop 3.0.0 alpha1+ change default nn port to 9820. See HDFS-9427
      testIsSameHdfs(9820);
    } else {
      // pre hadoop 3.0.0 defaults to port 8020
      testIsSameHdfs(8020);
    }
{code}

But in Hadoop 3.0.1, they decided to go back to the old port - see HDFS-12990.

So our tests will fail against the snapshot and against future releases.
