Subject Re: Could not build up connection to JobManager - Error
Date Sun, 22 Feb 2015 15:50:28 GMT
It seams the problem is with running WordCount.jar. I could run KMeans.jar without any problems.
May be I’ve passed the arguments incorrect.

bin/flink run ./examples/flink-java-examples-0.9-SNAPSHOT-WordCount.jar file://'pwd'/hemlet.txt
file://'pwd'/wordcount-result.txt
