> Currently, if we want to read file store on HDFS, we will do it as follow:
> {code}
> Configuration conf = new Configuration();
> conf.set("fs.default.name", "hdfs://hadoopserver:8020");
> HadoopFileSystemOptions options = ...
> options.setHdfsConfiguration(ImmutableList.of(conf));
> Pipeline p = Pipeline.create(options);
> PCollection<String> data = p.apply(TextIO.read().from("hdfs://hadoopserver:8020/tmp/data.txt"));
> {code}
> As we have seen above, we must be load/build the configuration and set it.
