> I don't know if our spark streaming issue is related to this (https://issues.apache.org/jira/browse/SPARK-15558).
> Basically we have one Kafka receiver on each executor, and it ran fine for a while. Then, the executor had a lot of waiting thread accumulated (Thread 1224: block-manager-slave-async-thread-pool-1083 (TIMED_WAITING)). And the executor kept open such new thread. Eventually, it reached the maximum number of the thread on that executor and Kafka receiver on that executor failed.
> Could someone please shed some light on this?
