> We have set the config Minimum Pause Between Checkpoints to be 10 min but
> noticed that when a checkpoint fails (because it timesout before it
> completes) the application immediately starts taking the next checkpoint.
> This basically stalls the application's progress since its always taking
> checkpoints.
> [^Screen Shot 2018-06-20 at 7.44.10 AM.png] is a screenshot of this issue.
> Details:
> * Running Flink-1.3.2 on EMR
> * checkpoint timeout duration: 40 min
> * minimum pause between checkpoints: 10 min
> There is also a [relevant
> thread|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Having-a-backoff-while-experiencing-checkpointing-failures-td20618.html]
