             Summary: Make Block Commit Sequence (BCS) opaque to clients
                 Key: HDDS-710
                 URL: https://issues.apache.org/jira/browse/HDDS-710
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: Ozone Client
            Reporter: Arpit Agarwal
            Assignee: Arpit Agarwal


An immutable block is identified by the following:
- Container ID
- Local Block ID
- BCS (Block Commit Sequence ID)

All of these values are currently exposed to the client. Instead we can have a 
composite block ID that hides these details from the client. A first thought is 
a naive implementation that generates a 192-bit (3x64-bit) block ID.

Proposed by [~anu] in HDDS-676.
