Subject Re: Spark/Kafka Streaming Job Gets Stuck
Date Wed, 28 Oct 2015 20:53:04 GMT
Does it work as expected with smaller batch or smaller load? Could it be that it's accumulating
too many events over 3 minutes?

You could also try increasing the parallelism via repartition to ensure smaller tasks that
can safely fit in working memory.
