--------------------------
Resolution: Invalid
> hasRowtimeAttribute will throw NPE if user use setProctimeAttribute for table
> source

> Key: FLINK-9329
> URL: https://issues.apache.org/jira/browse/FLINK-9329
> Project: Flink
> Issue Type: Bug
> Components: Table API & SQL
> Reporter: yuemeng
> Assignee: yuemeng
> Priority: Critical
>
> {code:java}
> Examples:
> KafkaTableSource source = Kafka010JsonTableSource.builder()
> .withSchema(TableSchema.builder()
> .field("sensorId", Types.LONG())
> .field("temp", Types.DOUBLE())
> .field("ptime", Types.SQL_TIMESTAMP()).build())
> .withProctimeAttribute("ptime")
> .build(); tableEnv.registerTableSource("flights", source ); {code}
> {{ }}
> {code:java}
> Kafka010JsonTableSource implement the DefinedRowtimeAttributes .
> so when TableSourceUtil call hasRowtimeAttribute(source)to check ,it will
> call follow code
> /** Returns a list with all rowtime attribute names of the [[TableSource]]. */
> private def getRowtimeAttributes(tableSource: TableSource[_]): Array[String]
> = {
> tableSource match {
> case r: DefinedRowtimeAttributes =>
> r.getRowtimeAttributeDescriptors.asScala.map(_.getAttributeName).toArray
> case _ =>
> Array()
> }
> }
> r.getRowtimeAttributeDescriptors will throw NPE because of we use
> ProctimeAttribute here
> {code}
