[jira] [Created] (FLINK-5407) Savepoint for iterative Task fails.
Stephan Ewen created FLINK-5407:
-----------------------------------
Summary: Savepoint for iterative Task fails.
Key: FLINK-5407
URL: https://issues.apache.org/jira/browse/FLINK-5407
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.2.0
Reporter: Stephan Ewen
Fix For: 1.2.0, 1.3.0
Flink 1.2-SNAPSHOT (Commit: 5b54009) on Windows.
Triggering a savepoint for a streaming job, both the savepoint and the job failed.
The job failed with the following exception:
