Tathagata Das created SPARK-23484:
-------------------------------------

             Summary: Fix possible race condition in KafkaContinuousReader
                 Key: SPARK-23484
                 URL: https://issues.apache.org/jira/browse/SPARK-23484
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 2.3.0
            Reporter: Tathagata Das
            Assignee: Tathagata Das


var `KafkaContinuousReader.knownPartitions` should be threadsafe as it is accessed from multiple threads - the query thread at the time of reader factory creation, and the epoch tracking thread at the time of `needsReconfiguration`.
