----------------------------------
Summary: SCM should remove pipeline before DN
Key: HDDS-12801
URL: https://issues.apache.org/jira/browse/HDDS-12801
Project: Apache Ozone
Issue Type: Improvement
Reporter: Aryan Gupta
Assignee: Aryan Gupta
Currently, SCM first fires the pipeline close command to DN and then, without
waiting for ACK, removes the pipeline from its state map.
Sometimes, we observed that the pipeline got removed from the DN but didn't get
removed from SCM, so it caused the SCM to get stuck in safemode as SCM is
expecting the pipelines from DN. So, first, we should remove the pipeline from
the SCM pipeline statemap and then fire the close pipeline command to DN.
