                 Key: BEAM-391
                 URL: https://issues.apache.org/jira/browse/BEAM-391
             Project: Beam

gcsio got stuck with invalid bucket name

GcsBufferedWriter._start_upload (gcsio.py) raises an exception if the bucket does not exist. This causes upload thread to silenty fail. It logs exception to the log but this does not stop the pipeline or closes the receiving end of the multiprocessing.Pipe(). Later a call in to write() blocks at self.conn.send_bytes(). Note that send may block if the buffer is full.

Upload thread should have a finally clause to close the socket connection. Or better propagating the exception to its parent. This is true for other types of exceptions also.

Another small issue in the GcsBufferedWriter.close(). It does not self self.close to True.

reproduction: python -m apache_beam.examples.wordcount --output gs://no-such-thing/

Prints the exception but goes on forever. Ctrl + C breaks the main thread shows where it got stuck.

Similarly reproducible on the service.
