[jira] [Created] (SPARK-40294) Repeat calls to `PartitionIterator.hasNext` can timeout

Richard Chen created SPARK-40294:
------------------------------------

             Summary: Repeat calls to `PartitionIterator.hasNext` can timeout
                 Key: SPARK-40294
                 URL: https://issues.apache.org/jira/browse/SPARK-40294
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.3.0
            Reporter: Richard Chen


Repeat calls to {{PartitionIterator.hasNext}} where both calls return {{false}} can result in timeouts. For example, {{{}KafkaBatchPartitionReader.next(){}}}, which calls {{consumer.get}} (which can potentially timeout with repeat calls), is called by {{{}PartitionIterator.hasNext{}}}. Thus, repeat calls to {{PartitionIterator.hasNext}} by its parent could timeout.
