> I have the same code: 
> BeamConfiguration.beamConfiguration();
> HadoopFileSystemOptions options = PipelineOptionsFactory.as(HadoopFileSystemOptions.class);
> options.setHdfsConfiguration(Collections.singletonList(config));
> options.setRunner(SparkRunner.class);
> Pipeline pipeline = Pipeline.create(options);
>  PCollection<String> recordsFromHdfs = pipeline.apply(TextIO.read().from(inputPath));
> nextPCollection = recordsFromHdfs......
> PCollection<String> recordsToHdfs = nextPCollection.apply(ParDo.of(new OutputHdfsFileFn(delimit)));
> recordsToHdfs.apply(TextIO.write().to(outputPath));
> pipeline.run().waitUntilFinish();
> one run successfully,but another throw exception like this:17/05/26 12:02:38 ERROR yarn.ApplicationMaster:

(reason: User class threw exception: java.lang.IllegalStateException: Unable to find registrar

> I find it will setDefaultPipelineOptions(PipelineOptions options) using hdfs,why I always
get execuption ?
