[jira] [Assigned] (SPARK-32091) Ignore timeout error when remove
blocks on the lost executor

> ------------------------------------------------------------
>
> Key: SPARK-32091
> URL: https://issues.apache.org/jira/browse/SPARK-32091
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0, 3.0.0
> Reporter: wuyi
> Priority: Major
>
> When removing blocks(e.g. RDD, broadcast, shuffle), BlockManagerMaserEndpoint will make RPC calls to each known BlockManagerSlaveEndpoint to remove the specific blocks. The PRC call sometimes could end in a timeout when the executor has been lost, but only notified the BlockManagerMasterEndpoint after the removing call has already happened. The timeout could therefore fail the whole query.
> In this case, we actually could just ignore the error since those blocks on the lost executor could be considered as removed already.
