Hello Kamal, - How to tell Ignite to move a clustered singleton service from one node to another with external scripts?
What are you mean when say: "move a clustered singleton service from one node to another"? If singleton service was deployed on cluster group, it will stay until, last node leaves the cluster. In case the cluster node on which the service was deployed crashes or stops, Ignite will automatically redeploy it on another node.
