Subject java.nio.channels.ClosedChannelException in Spark Streaming KafKa Direct
Date Mon, 01 Feb 2016 15:59:23 GMT
Hi,

I see the following error in Spark Streaming with Kafka Direct. I think that
this error is related to Kafka topic. Any suggestions on how to avoid this
error would be of great help.
