Hi Theodore and Vasia,
Thanks for your reply.
I can compile my code by add dependency jars manually.
Yes, in my code, I already import Flink-scala (import
org.apache.flink.api.scala._).
However when I run my code,
I get the following error:
*ava.lang.NoSuchMethodError:
org.apache.flink.api.scala.ExecutionEnvironment.getJavaEnv()Lorg/apache/flink/api/java/ExecutionEnvironment;
at org.apache.flink.graph.scala.Graph$.fromDataSet(Graph.scala:53)*
any suggestions?
Thanks,
Do
