[jira] [Created] (SPARK-40250) Further check the availability of RemoteBlockPushResolver API after call close

Yang Jie created SPARK-40250:
--------------------------------

             Summary: Further check the availability of RemoteBlockPushResolver API after call close
                 Key: SPARK-40250
                 URL: https://issues.apache.org/jira/browse/SPARK-40250
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.4.0
            Reporter: Yang Jie


Call the API of RemoteBlockPushResolver after it has been closed is a dangerous behavior.

For example, `applicationRemoved` will try to delete data from a closed DB instance, and when the DB instance is RocksDB, JVM will crash.

 

It needs to further check whether this scenario is possible.
