> 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.
