I get the NPE from the below code
I am running this from my mac in a local flink cluster.
RollingSink<String> s3Sink = new RollingSink<String>("s3://sc-sink1/");
s3Sink.setBucketer(new DateTimeBucketer("yyyy-MM-dd--HHmm"));
s3Sink.setWriter(new StringWriter<String>());
s3Sink.setBatchSize(200);
s3Sink.setPendingPrefix("file-");
s3Sink.setPendingSuffix(".txt");
outStream.addSink(s3Sink).setParallelism(1);
causes
java.lang.NullPointerException

I even tried changing s3:// path to a local path, same issue
The below works and spits out the stream, and the stream has data.
outStream.writeAsText("/Users/schowdhury/flink/kinesisread"+System.currentTimeMillis());
am I missing something obvious?looks like it is trying to create a folder.
