             Summary: Cluster ID and tag: properties to identify the cluster
                 Key: IGNITE-12111
                 URL: https://issues.apache.org/jira/browse/IGNITE-12111
             Project: Ignite
          Issue Type: New Feature
            Reporter: Sergey Chugunov
            Assignee: Sergey Chugunov
             Fix For: 2.8


To improve cluster management capabilities two new properties of the cluster are introduced:

# A unique cluster ID (may be either a random UUID or random IgniteUUID). Generated upon cluster start and saved to the distributed metastorage. Immutable. Persistent clusters must persist the value. In-memory clusters should keep the generated ID in memory and regenerate it upon restart.
# Human-readable cluster tag. Generated by default to some random (but still meaningful) string, may be changed by user. Again survives restart in persistent clusters and is regenerated in in-memory clusters on every restart.

These properties are exposed to standard APIs:
# EVT_CLUSTER_TAG_CHANGED event generated when tag is changed by user;
# JMX bean and control utility APIs to view ID and tag and change tag.
