> 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.
