>                 Key: SPARK-3289
>                 URL: https://issues.apache.org/jira/browse/SPARK-3289
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>            Reporter: Josh Rosen

> Some users have reported issues where a task fails due to an environment / configuration
issue on some machine, then the task is reattempted _on that same buggy machine_ until the
entire job failures because that single task has failed too many times.
> To guard against this, maybe we should add some randomization in how we reschedule failed
tasks.
