Re: [Possible Bug] Savepoints Akka Timeout

Hi Sayat,

I think your problem might be caused by
https://issues.apache.org/jira/browse/FLINK-10193. This will be fixed with
the next bug fix release which will happen in the next days.

In the future, please post these kind of questions to user@xxxxxxxxxxxxxxxx.
The dev mailing list is intended for Flink development discussions.
