             Summary: Suspending Pipeline Breaks FlinkBlueGreenDeployment
                 Key: FLINK-38915
                 URL: https://issues.apache.org/jira/browse/FLINK-38915
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
            Reporter: Daniel Rossos


*Current Behaviour*

Setting "spec.template.spec.job.state" to "suspended" in FlinkBlueGreenDeployment triggers a broken transition. The controller triggers a blue-green transition that creates a new suspended deployment which then fails because the new 'green' pipeline never reaches running state. This creates a broken transition. 

*Proposed Solution*

The BlueGreen deployment should properly handle these transitions to "suspension state". The proposed method (as discussed in discussion thread [here|https://lists.apache.org/thread/0hhct3ktws3wv9psrgyro0kdy8g1hjnq]) is as follows:

State changes to "spec.template.spec.job.state" trigger in-place suspension of the active child. While suspended, all blue-green transitions are ignored until spec is set back to running. Once running again, spins up new deployment with any accumulated spec changes and resumes normal blue-green operations.
