Robert Metzger created FLINK-3021:
-------------------------------------
Summary: Job submission times out due to classloading issue on
JobManager
Key: FLINK-3021
URL: https://issues.apache.org/jira/browse/FLINK-3021
Project: Flink
Issue Type: Bug
Components: JobManager
Affects Versions: 0.10.0
Reporter: Robert Metzger
Priority: Critical
A user reported the following issue when submitting a very simple job using the
{{DataStream}} API:
{code}
Caused by: org.apache.flink.runtime.client.JobExecutionException: Communication
with JobManager failed: Job submission to the JobManager timed out.
at
org.apache.flink.runtime.client.JobClient.submitJobAndWait(JobClient.java:141)
at org.apache.flink.client.program.Client.runBlocking(Client.java:368)
... 13 more
Caused by:
org.apache.flink.runtime.client.JobClientActorSubmissionTimeoutException: Job
submission to the JobManager timed out.

at akka.actor.Actor$class.aroundReceive(Actor.scala:465)
{code}
The problem is that akka can not deserialize the job submit message on the
JobManager. From the logs, the issue becomes apparent:
{code}

I suspect the issue is that the job is using an AvroInputFormat which holds a
reference to the POJO.
