From a glance I don't see anything obvious that would limit the concurrency of HDFS. It appears the HDFS filesystem will launch a new thread task for each read request. Do you have multiple CSV files or just one CSV file? Unfortunately, I do not have an HDFS test environment locally so it is hard for me to test / profile HDFS. You shouldn't need to do anything to get concurrent I/O. -- This is an automated message from the Apache Git Service.
