-------------------------------------
Summary: java.lang.ClassCastException: X cannot be cast to X
Key: FLINK-1390
URL: https://issues.apache.org/jira/browse/FLINK-1390
Project: Flink
Issue Type: Bug
Components: YARN Client
Affects Versions: 0.8
Reporter: Robert Metzger
A user is affected by an issue, which is probably caused by different
classloaders being used for loading user classes.
Current state of investigation:
- the error happens in yarn sessions (there is only a YARN environment
available)
- the error doesn't happen on the first time the job is being executed. It only
happens on subsequent executions.
