Hello, the compiler has been raising an error since I added this line to the code
val testData=streamEnv.addSource(new FlinkKafkaConsumer082[String]("data-input",new SimpleStringSchema(),kafkaProp)) Here is the error: Error:scalac: Class org.apache.flink.streaming.api.checkpoint.CheckpointNotifier not found - continuing with a stub. Error:scalac: Class org.apache.flink.streaming.util.serialization.KeyedDeserializationSchema not found - continuing with a stub. Warning:scalac: Class org.apache.flink.streaming.util.serialization.KeyedDeserializationSchema not found - continuing with a stub. Warning:scalac: Class org.apache.flink.streaming.api.checkpoint.CheckpointNotifier not found - continuing with a stub. I've been using the 1.0-Snapshot version built with scala 2.11. Any suggestion?
