> Dynamic allocation: avoid double counting when killing same executor
> --------------------------------------------------------------------
>
> 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
> Reporter: Andrew Or
> Assignee: Andrew Or
> 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.
