Gabor Somogyi created SPARK-29054:

             Summary: Invalidate Kafka consumer when new delegation token available
                 Key: SPARK-29054
                 URL: https://issues.apache.org/jira/browse/SPARK-29054
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 3.0.0
            Reporter: Gabor Somogyi


Kafka consumers are cached. If delegation token is used and the token is expired, then exception is thrown. Such case new consumer is created in a Task retry with the latest delegation token. This can be enhanced by detecting the existence of a new delegation token.
