>                 Key: SPARK-9795
>                 URL: https://issues.apache.org/jira/browse/SPARK-9795
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 1.4.0

>            Priority: Critical

> Currently, if we kill the same executor twice in rapid succession, we will lower the executor target by 2 instead of 1. In cases where we don't re-adjust the target upwards frequently, this will result in jobs hanging.
> This may or may not be the same as SPARK-9745. Until we can verify the correlation, however, this will remain a separate issue.
