Timo Walther created FLINK-5673:
-----------------------------------
Summary: NullPointerException in
RemoteInputChannel.requestSubpartition
Key: FLINK-5673
URL: https://issues.apache.org/jira/browse/FLINK-5673
Project: Flink
Issue Type: Bug
Components: Core
Reporter: Timo Walther
It might be related to FLINK-5672 but I'm opening an additional issue, because
it is a different exception after the second execution. The setup is identical
to FLINK-5672. But if I run the job a second time I got the following exception:
