Apache Flink InvocationTargetException: Job execution failed. Connection timed out

Question

I am creating this example from the quickstart guide for Apache Flink. I always keep getting the error:

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java (default-cli) on project wiki-edits: An exception occured while executing the Java class. null: InvocationTargetException: Job execution failed. Connection timed out -> [Help 1]

with a lot of exceptions coming from Flink's internal files and not the file I am coding. Can anyone give a solution to this problem?

Here is the full exception:

Can you post the exceptions coming from Flink's internal files? This will make it easier to answer your question. — Robert Metzger

It looks like the WikipediaEditsSource can not establish the connection to the IRC channel containing the Wikiedits.

The source is subscribing to an IRC channel where Wikipedia is posting edits. It may be possible that the typical IRC ports (6667, 6668, ..) are blocked in your network.

Can you check whether you can reach irc.wikimedia.org:6667 from your network? The channel is #en.wikipedia.
