             Summary: one throw "Unable to find registrar for hdfs" with same code
                 Key: BEAM-2368
                 URL: https://issues.apache.org/jira/browse/BEAM-2368
             Project: Beam

          Components: runner-spark
            Reporter: liyuntian
            Assignee: Amit Sela


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

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