             Summary: Do not use deleted block count to determine if containers 
are empty
                 Key: HDDS-8115
                 URL: https://issues.apache.org/jira/browse/HDDS-8115
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Ethan Rose
            Assignee: Ethan Rose


Ozone currently uses a block count metadata field for each container replica to 
determine whether it is empty. This counter can be incorrect in some cases and 
is difficult to maintain. It is only used to determine whether the container is 
empty. In this case, it would be simpler to have a an isEmpty boolean for each 
container that starts as {{false}} and is set to {{true}} when a delete block 
is processed and the block table is empty.
