---------------------------------
Summary: Make 'replicas' work in JobManager Spec
Key: FLINK-26216
URL: https://issues.apache.org/jira/browse/FLINK-26216
Project: Flink
Issue Type: Bug
Components: Kubernetes Operator
Reporter: Biao Geng
In our flink kubernetes operator's cr, we allow users to set the replica of
JobManager.
But in our {{FlinkUtils#getEffectiveConfig}} method, we currently not set this
value from the yaml file and as a result, the {{replicas}} will not work and
the default value(i.e. 1) will be applied.
Though we believe one JM with KubernetesHaService should be enough for most HA
cases, the {{replicas}} field of JM also makes sense since more than one JM can
reduce down time and make recovery of JM failure faster.
