------------------------------------------
Summary: Heartbeat with large accumulator payload may cause
instable clusters
Key: FLINK-15252
URL: https://issues.apache.org/jira/browse/FLINK-15252
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Reporter: Maximilian Michels
We've seen timeouts which look like they are induced by large accumulator
payloads. Removing the accumulators stabilized the cluster.
IMHO the heartbeat should not contain the accumulator payload. Accumulators
should be handled separately.
