[jira] [Created] (SPARK-27111) A continuous query may fail with InterruptedException when kafka consumer temporally 0 partitions temporally

------------------------------------

             Summary: A continuous query may fail with InterruptedException when kafka consumer temporally 0 partitions temporally
                 Key: SPARK-27111
                 URL: https://issues.apache.org/jira/browse/SPARK-27111
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 2.3.3, 2.3.2, 2.3.1, 2.3.0
            Reporter: Shixiong Zhu
            Assignee: Shixiong Zhu


Before a Kafka consumer gets assigned with partitions, its offset will contain 0 partitions. However, runContinuous will still run and launch a Spark job having 0 partitions. In this case, there is a race that epoch may interrupt the query execution thread after `lastExecution.toRdd`, and either `epochEndpoint.askSync[Unit](StopContinuousExecutionWrites)` or the next `runContinuous` will get interrupted unintentionally.
