[jira] [Comment Edited] (SPARK-7236) AkkaUtils askWithReply sleeps
indefinitely when a timeout exception is thrown
[ https://issues.apache.org/jira/browse/SPARK-7236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14519862#comment-14519862 ]

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

> 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}}.
