----------------------------------
Summary: Misleading error message when migrating and scaling down
from savepoint
Key: FLINK-5440
URL: https://issues.apache.org/jira/browse/FLINK-5440
Project: Flink
Issue Type: Improvement
Components: State Backends, Checkpointing
Reporter: Ufuk Celebi
Priority: Minor
When resuming from an 1.1 savepoint with 1.2 and reducing the parallelism (and
correctly setting the max parallelism), the error message says something about
a missing operator which is misleading. Restoring from the same savepoint with
the savepoint parallelism works as expected.
Instead it should state that this kind of operation is not possible.
