Here is my test code , this example is from official website.
```scala
val spark = SparkSession.builder()
.master("local")
.getOrCreate()
val df = spark.readStream
.option("kafka.bootstrap.servers", kafkaServers)
.option("startingOffsets", "latest")
.option("subscribe", kafkaTopics)
.format("kafka")
.option("failOnDataLoss", false)
.load()
df.selectExpr("CAST(timestamp AS STRING)", "CAST(partition as STRING) as
f2")
.writeStream
.format("doris")
.option("checkpointLocation", "/tmp/test")
.option("doris.table.identifier", dorisTable)
.option("doris.fenodes", dorisFeNodes)
.option("user", dorisUser)
.option("password", dorisPwd)
.option("doris.write.fields","f1,f2")
.option("sink.batch.size",2)
.option("sink.max-retries",2)
.start().awaitTermination()
spark.stop()
```
The above code runs with the following exception:
```
