Hi Robert, Thanks for your answer. Do you mean the log file in (e.g.) flink-0.10.0/log/flink-hadoop-client-ip-172-31-10-193.log? Or you mean another log file?
In this log, the error message is as follows: 08:16:03,437 INFO org.apache.flink.runtime.client.JobClient - Job execution complete 08:16:03,438 INFO org.apache.flink.api.java.ExecutionEnvironment - The job has 5 registered types and 0 default Kryo serializers 08:16:03,444 INFO org.apache.flink.runtime.client.JobClientActor -

Maybe there you can find helpful information why it failed. On Wed, Jan 20, 2016 at 3:23 PM, Ana M.

Sometimes when it fails, I just try to run it again immediately afterwords and it works fine. Any idea on why that might be happening? Thanks, Ana
