> When I use Flink SQL scala API, I found a bug. I have a sensor.txt, the txt file has some sensor data.One row of data is as follows:
> {code:java}
> sensor_1,1547718199,35.8
> {code}
> And I have a `package object MyTest` class. This class has a case class `SensorReading`.
> {code:java}
> package object MyTest {
>     case class SensorReading(id: String, timestamp: Long, temperature: Double)
> }
> {code}
> When I use Flink SQL API, I think he should output the correct result, but he reported an error.
> {code:java}
> tEnv.createTemporaryView("ds", dataStream)
> val result: Table = tEnv.sqlQuery("SELECT * FROM ds where `temperature` >= 5")
> result.toAppendStream[SensorReading].print("test"){code}
> I will send you the error as a file later. And I found Inner class and scala General class not send this error.
> If you have any findings, please contact me.
