             Summary: Implement option to skip null values in symmetric hash impl of stream-stream joins
                 Key: SPARK-38809
                 URL: https://issues.apache.org/jira/browse/SPARK-38809
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 3.2.1
            Reporter: Anish Shrigondekar


Implement option to skip null values in symmetric hash impl of stream-stream joins
 * In the symmetric has join state manager, we can receive entries with null values for a key and that caused the `removeByValue` and get iterators to fail and run into the NullPointerException.
 * This is possible if the state recovered is written from a old spark version or its corrupted on disk. Since we don't have a utility to query this state, we would like to provide a conf option to skip nulls for the symmetric hash impl in stream stream joins.
