Subject Re: Apache Flink 1.1.4 - Java 8 - CommunityDetection.java:158 - java.lang.NullPointerException
Date Mon, 16 Jan 2017 14:10:10 GMT
Hi Miguel,

thank you for opening the issue!
Changes/improvements to the documentation are also typically handled with
JIRAs and pull requests [1]. Would you like to give it a try and improve
the community detection docs?

Cheers,
-Vasia.
