You can reproduce it with below query in spark-shell, with continuously pushing records to topic1 and topic2. > > ``` > val bootstrapServers = "localhost:9092" > val checkpointLocation = "/tmp/SPARK-28869-testing" > val sourceTopics = "topic1" > val sourceTopics2 = "topic2" > val targetTopic = "topic3" > > val df = spark.readStream.format("kafka").option("kafka.bootstrap.servers", bootstrapServers).option("subscribe", sourceTopics).option("startingOffsets", "earliest").load() > > val df2 = spark.readStream.format("kafka").option("kafka.bootstrap.servers", bootstrapServers).option("subscribe", sourceTopics2).option("startingOffsets", "earliest").load() > > df.union(df2).writeStream.format("kafka").option("kafka.bootstrap.servers", bootstrapServers).option("checkpointLocation", checkpointLocation).option("topic", targetTopic).start() > ``` is there a separate jira on this?
