----------------------------------
Summary: Failed to submit JobGraph Apache Flink on Github Master
Branch
Key: FLINK-8795
URL: https://issues.apache.org/jira/browse/FLINK-8795
Project: Flink
Issue Type: Bug
Reporter: kant kodali
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?
I followed the instructions from the Flink master branch so I did the following.
{{git clone https://github.com/apache/flink.git }}
{{cd flink mvn clean package -DskipTests }}
{{cd build-target }}
{{./bin/start-scala-shell.sh local}}
{{And Here is the code I ran}}
{code:java}
val dataStream = senv.fromElements(1, 2, 3, 4)
dataStream.countWindowAll(2).sum(0).print()
senv.execute("My streaming program"){code}
{{And I finally get this exception}}
{{}}
{code:java}
