-----------------------------------
Resolution: Fixed
> Failed executor not properly removed if it has not run tasks
> ------------------------------------------------------------
>
> Key: SPARK-4020
> URL: https://issues.apache.org/jira/browse/SPARK-4020
> Project: Spark
> Issue Type: Bug
> Reporter: Andrew Or
> Assignee: Andrew Or
> Fix For: 1.2.0
>
>
> If an executor has not run tasks, then the DAG scheduler won't remove the
> block manager that belongs to this executor. This is because we don't add the
> executor to `activeExecutorIds` in `TaskSchedulerImpl` until we have
> successfully scheduled a task on the executor.
> The motivation for fixing this is to avoid having the
> `BlockManagerMasterActor` to remove the associated block manager through a
> timeout when it can just do so right away.
