This is my code to read csv
//DataflowPipelineOptions options = PipelineOptionsFactory.as(DataflowPipelineOptions.class);
PipelineOptions options=PipelineOptionsFactory.create();
//options.setProject("ProjectId");
//options.setStagingLocation("gs://bucketname/Object");
options.setRunner(DirectRunner.class);
options.setTempLocation("gs://bucketname/Object");
Pipeline p = Pipeline.create(options);
p.apply(FileIO.match().filepattern("gs://bucketname/objectname.csv")).apply(FileIO.readMatches())
.apply(ParDo.of(new checkSplitter()));
p.run();
}
static class checkSplitter extends DoFn<ReadableFile, String> {
/**
*
*/
private static final long serialVersionUID = 1L;
int rown = 1;
String line;
@ProcessElement
public void processElement(ProcessContext c) throws Exception {
try (InputStream is = Channels.newInputStream(c.element().open())) {
BufferedReader bReader = new BufferedReader(new InputStreamReader(is));
while ((line = bReader.readLine()) != null) {
System.out.println(line);
}
}
}
}
