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.
