How to Set Retry Policy in Spark

[Renxia Wang]

Hi guys,

I know there is a way to set the number of retry of failed tasks, using
spark.task.maxFailures. what is the default policy for the failed tasks
retry? Is it exponential backoff? My tasks sometimes failed because of
Socket connection timeout/reset, even with retry, some of the tasks will
fail for more than spark.task.maxFailures times.

Thanks,

Zhique
