> -------------------------------------------
>
> Key: SPARK-21147
> URL: https://issues.apache.org/jira/browse/SPARK-21147
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.1.0
> Environment: Win7,spark 2.1.0
> Reporter: Fei Shao
>
> The schema set for DataStreamReader can not work. The code is shown as below:
> val line = ss.readStream.format("socket")
> .option("ip",xxx)
> .option("port",xxx)
> .schema( StructField("name",StringType)::StructField("area",StringType)::Nil)
> .load
> line.printSchema
> The printSchema prints:
> root
> |--value:String(nullable=true)
> According to the code, it should print the schema set by schema().
> Suggestion from Michael Armbrust:
> throw an exception saying that you can't set schema here.
