------------------------------------
Summary: Change default OM Node ID from UUID to a constant
Key: HDDS-4680
URL: https://issues.apache.org/jira/browse/HDDS-4680
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
If a nodeID is not set explicitly (for a single node OM cluster), then it
defaults to the OM storage ID which is an UUID string. Proposing to change this
default to a constant (such as "om1") instead.
This would help when a cluster is upgraded to HA for example. It is not
straightforward to change the nodeID after Ratis server has been instantiated
(as the nodeID is used to generate the RaftPeerID). Hence, it would be good to
have a more readable nodeID by default.
