Issue XD-623: catch erroneous hadoop config fs --namenode url early
currently, we can specify any bogus url using 'hadoop config fs --namenode' without any warning. e.g. hadoop config fs --namenode hdfs://localhost:8888 doing a 'hadoop fs ls /' will catch the error and throw exception. Ideally, we should catch the bogus url error early in the 'hadoop config fs' command. similar to 'admin config server --uri'
