We are running a Kafka Consumer in local mode using Spark Streaming,
KafkaUtils.createDirectStream.
The job runs as expected, however once in a very long time time, I see the
following exception.
Wanted to check if others have faced a similar issue, and what are the right
timeout parameters to change to avoid this issue.
Job aborted due to stage failure: Task 5 in stage 30499.0 failed 1 times,
most recent failure: Lost task 5.0 in stage 30499.0 (TID 203307, localhost):

When this failure happens, the executor is not retried either.
Any help appreciated.
