             Summary: Make OM KeyDeletingService compatible with HA model
                 Key: HDDS-1775
                 URL: https://issues.apache.org/jira/browse/HDDS-1775
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


Currently OM KeyDeletingService directly deletes all the keys in DeletedTable 
after deleting the corresponding blocks through SCM. For HA compatibility, the 
key purging should happen through the OM Ratis server. This Jira introduces 
PurgeKeys request in OM protocol. This request will be submitted to OMs Ratis 
server after SCM deletes blocks corresponding to deleted keys.
