----------------------------------

             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?
