Subject Re: Error submitting stand-alone Flink job to EMR YARN cluster
Date Sun, 03 Jul 2016 16:04:03 GMT
Hi Bruce,

I just spun up an EMR cluster and tried this out.  Hadoop 2.7.2 and Flink
1.0.3.  I ran the exact same command as you and everything works just fine.

Please verify one thing, though.  In your command you do not specify the
path to the Flink executable, which means it's just getting picked up from
your PATH.  Is it possible you're running a flink-1.0.3 example program but
using a different version of Flink?  Try the following:

./flink-1.0.3/bin/flink run -m yarn-cluster -yn 1 -ynm test1:WordCount
./flink-1.0.3/examples/streaming/WordCount.jar

​
