Ufuk Celebi created FLINK-5467:
----------------------------------
Summary: Stateless chained tasks set legacy operator state
Key: FLINK-5467
URL: https://issues.apache.org/jira/browse/FLINK-5467
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Reporter: Ufuk Celebi
I discovered this while trying to rescale a job with a Kafka source with a
chained stateless operator.
Looking into it, it turns out that this fails, because the checkpointed state
contains legacy operator state for the chained operator although it is state
less.
/cc [~aljoscha] You mentioned that this might be a possible duplicate?
