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.
