[jira] [Created] (HDDS-1053) Generate RaftGroupId from OMServiceID

Hanisha Koneru created HDDS-1053:
------------------------------------

             Summary: Generate RaftGroupId from OMServiceID
                 Key: HDDS-1053
                 URL: https://issues.apache.org/jira/browse/HDDS-1053
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


Ratis requires {{RaftGroupId}} to be a UUID. We need to generate this ID from the {{OMServiceID}} so that it is consistent across all the OM nodes in a HA service.

Currently, we expect {{OMServiceId}} to be a 16 character string so that it can be converted to a UUID. But {{OMServiceID}} is a user configurable setting. Hence we cannot force users to input a 16 character string.

One option is to hash the \{{OMServiceID}} string then truncate to UUID length and use that to generate the UUID.
