Apache Spark reassigned SPARK-27234:
------------------------------------
Assignee: Apache Spark
> Continuous Streaming does not support python UDFs
> -------------------------------------------------
>
> Key: SPARK-27234
> URL: https://issues.apache.org/jira/browse/SPARK-27234
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.4.0
> Environment: Azure Databricks 5.1
> Reporter: Mark Hamilton
> Assignee: Apache Spark
> Priority: Major
>
> Heres a repro:
> {code:java}
> from pyspark.sql.functions import col, udf
> fooUDF = udf(lambda p: "foo")
> spark \
> .readStream \
> .format("rate") \
> .load()\
> .withColumn("foo", fooUDF(col("value")))\
> .writeStream\
> .format("console")\
> .trigger(continuous="1 second").start() {code}
> Error Message (All that Azure Databricks prints):
