             Summary: DistributedCache alternative APIs should not use DistributedCache APIs internally
                 Key: MAPREDUCE-7371
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7371
             Project: Hadoop Map/Reduce
          Issue Type: Task
            Reporter: Viraj Jasani
            Assignee: Viraj Jasani


DistributedCache has been deprecated long back and it's still being used as of today. However, all the alternative Job APIs (for deprecated DistributedCache APIs) still internally use DistributedCache APIs only, this is a deadlock and it leaves no room for removal of DistributedCache APIs in future. We should move core logic to Job or JobContext as required and let deprecated DistributedCache APIs point to the right alternatives internally.
