> After HDFS-8180, TestWebHdfsFileContextMainOperations and
> TestSWebHdfsFileContextMainOperations are failing with runtime NPEs while
> instantiating the wrapped WebHDFSFileSystems because {{getDefaultPort}} is
> trying to access a conf that was never provided. In the constructor both
> both WebHdfs and SWebhdfs the underlying (S)WebHdfsFileSystems are
> instantiated in the constructor and never have a chance to have their
> {{setConf}} methods called:
> {code} SWebHdfs(URI theUri, Configuration conf)
> throws IOException, URISyntaxException {
> super(theUri, new SWebHdfsFileSystem(), conf, SCHEME, false);
> }r{code}
> The test passes on trunk because HDFS-5321 removed the call to the
> Configuration instance as part of {{getDefaultPort}}. HDFS-5321 was applied
> to branch-2 but reverted in HDFS-6632, so there's a bit of a difference in
> how branch-2 versus trunk handles default values (branch-2 pulls them from
> configs if specified, trunk just returns the hard-coded value from the
> constants file).
> I've fixed this behave like trunk and return just the hard-coded value, which
> causes the test to pass.
> There is no WebHdfsFileSystem that takes a Config, which would be another
> way to fix this.
