Another alternative is to write block sized chunks into multiple hdfs files concurrently followed by concat to all those into a single file.

Ch,
you may consider using flume as it already has a flume sink that can sink
to hdfs. What I did is to set up a flume listening on an Avro sink, and
then sink to hdfs. Then in my application, i just send my data to avro
socket.

you may consider using flume as it already has a flume sink that can sink
to hdfs. What I did is to set up a flume listening on an Avro sink, and
