Could not upload the jar files to the job manager IOException

Hi all,

I am running some experiments with flink in an Amazon cluster and every now and then (it seems to appear at random) I get the following IOException:
> org.apache.flink.client.program.ProgramInvocationException: The program execution failed: Could not upload the jar files to the job manager.

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
