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

             Summary: DistributedFileSystem#getCanonicalServiceName() and DistributedFileSystem#getUri() may return inconsistent results w.r.t. port
                 Key: HDFS-6092
                 URL: https://issues.apache.org/jira/browse/HDFS-6092
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.3.0
            Reporter: Ted Yu


I discovered this when working on HBASE-10717
Here is sample code to reproduce the problem:
{code}
    Path desPath = new Path("hdfs://127.0.0.1/");
    FileSystem desFs = desPath.getFileSystem(conf);
    
    String s = desFs.getCanonicalServiceName();
    URI uri = desFs.getUri();
{code}
Canonical name string contains the default port - 8020
But uri doesn't contain port.
This would result in the following exception:
{code}
testIsSameHdfs(org.apache.hadoop.hbase.util.TestFSHDFSUtils)  Time elapsed: 0.001 sec  <<< ERROR!
java.lang.IllegalArgumentException: port out of range:-1
        at java.net.InetSocketAddress.checkPort(InetSocketAddress.java:143)
        at java.net.InetSocketAddress.<init>(InetSocketAddress.java:224)
        at org.apache.hadoop.hbase.util.FSHDFSUtils.getNNAddresses(FSHDFSUtils.java:88)
{code}
