----------------------------
Summary: 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: 3.0.0, 2.4.0
Reporter: wuyi
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 BlockManagerSlaveEndpoint 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.
