Bryan Cutler commented on SPARK-7236:
-------------------------------------
According to git blame, it looks like the default of {{retryInterval =
Int.Max}} was added with SPARK-3822
https://github.com/apache/spark/commit/1df05a40ebf3493b0aff46d18c0f30d2d5256c7b.
Maybe [~andrewor14] can comment if this was done for a specific reason?

> Key: SPARK-7236
> URL: https://issues.apache.org/jira/browse/SPARK-7236
> Project: Spark
> Issue Type: Bug

>
> When {{AkkaUtils.askWithReply}} gets a TimeoutException, the default
> parameters {{maxAttempts = 1}} and {{retryInterval = Int.Max}} lead to the
> thread sleeping for a good while.
> I noticed this issue when testing for SPARK-6980 and using this function
> without invoking Spark jobs, so perhaps it acts differently in another
> context.
> If this function is on its final attempt to ask and it fails, it should
> return immediately. Also, perhaps a better default {{retryInterval}} would
> be {{0}}.
