## What changes were proposed in this pull request? This problem reported by yanlin-Lynn ivoson and LiangchangZ. Thanks! When we union 2 streams from kafka or other sources, while one of them have no continues data coming and in the same time task restart, this will cause an `IllegalStateException`. This mainly cause because the code in [MicroBatchExecution](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/MicroBatchExecution.scala#L190) , while one stream has no continues data, its comittedOffset same with availableOffset during `populateStartOffsets`, and `currentPartitionOffsets` not properly handled in KafkaSource. Also, maybe we should also consider this scenario in other Source. ## How was this patch tested? Add a UT in KafkaSourceSuite.scala Author: Yuanjian Li <xyliyuanjian@gmail.com> Closes #20150 from xuanyuanking/SPARK-22956. |
