> Self-union streaming query may fail when using readStream.table
> ---------------------------------------------------------------
>
> Key: SPARK-41040
> URL: https://issues.apache.org/jira/browse/SPARK-41040
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.4.0
> Reporter: Shixiong Zhu
> Assignee: Shixiong Zhu
> Priority: Major
>
> In a self-union query, the batch plan created by the source will be shared by
> multiple nodes in the plan. When we transform the plan, the batch plan will
> be visited multiple times. Hence, the first visit will set the CatalogTable
> and the second visit will try to set it again and fail the query at [this
> line|https://github.com/apache/spark/blob/406d0e243cfec9b29df946e1a0e20ed5fe25e152/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/MicroBatchExecution.scala#L625].
