Re: java Flink local test failure (Could not create actor system)

Hi Vijay,

Since version 1.7 Flink builds with Scala version 2.11 (default) and 2.12.
Flink has APIs, libraries, and runtime modules written in Scala. Users of
the Scala API and libraries may have to match the Scala version of Flink
with the Scala version of their projects (because Scala is not strictly
backward compatible). See [1] for more information.

If using maven, artifactId of Flink components usually end with scala
version, such as flink-streaming-java_2.11 means it was built against Scala
2.11.
