-------------------------------------
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.
