> 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}
> Thanks to Brando Li who helped debug this.
