> Ensure there are shutdown hooks in place for the various oak-run commands that properly stop the repository and release the clusterId.
> Many command construct a repository, then perform some operation and then shut down the repository again. Shutting down the repository will release the clusterId change the state of the clusterNodes entry back to inactive. In some cases commands execute for a longer period of time and a user might kill the process. When this happens, the clusterId is not released and stays in the active state with a lease that eventually expires. The command implementations should be improved to register a JVM shutdown hook that ensures the repository is shut down, even when the process is killed.
