> 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].
