Could not upload the jar files to the job manager IOException

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 |

Hi, can you check the log file of the JobManager you're trying to submit the job to? Maybe there you can find helpful information why it failed. On Wed, Jan 20, 2016 at 3:23 PM, Ana M. Martinez <[hidden email]> wrote: Hi all, |

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 - Received job Flink Java Job at Thu Jan 21 08:16:03 UTC 2016 (73f8ab2fbab61fb72dc4a53fd8dcbb9f). 08:16:03,444 INFO org.apache.flink.runtime.client.JobClientActor - Could not submit job Flink Java Job at Thu Jan 21 08:16:03 UTC 2016 (73f8ab2fbab61fb72dc4a53fd8dcbb9f), because there is no connection to a JobManager. 08:16:03,446 INFO org.apache.flink.runtime.client.JobClientActor - Connected to new JobManager <a href="akka.tcp://flink@172.31.5.123:34614/user/jobmanager" class="" style="font-family: Menlo;

Actually, if I run it again it may or may not work. Ana

Hi, this is the log file of your local client submitting the job to Flink's JobManager (master). As you can see from the log, the jar upload failed because of this issue: "Caused by: java.net.SocketException: Connection reset". The JobManager is the service at the other end receiving the file. I'm pretty sure its logging why the connection has been reset. Maybe the JM jvm failed, the disk was full, there was an network issue .... The JobManager log file is located on the machine where the jobmanager is running. If you are using Flink on YARN, just get the aggregated application logs, and search for the "jobmanager.log" file.
