Alex Chen commented on FLINK-8795:
----------------------------------
Is it worth to document the workaround(for now) in
[https://ci.apache.org/projects/flink/flink-docs-master/dev/scala_shell.html] ?
If so, I'd like to do that.

> I am trying to run the simple code below after building everything from
> Flink's github master branch for various reasons. I get an exception below
> and I wonder what runs on port 9065? and How to fix this exception?

> following.

> git clone https://github.com/apache/flink.git
> cd flink mvn clean package -DskipTests
> cd build-target
> ./bin/start-scala-shell.sh local{code}
> {{And Here is the code I ran}}
