             Summary: Create ReplDumpTask/ReplDumpWork for dumping out metadata
                 Key: HIVE-15205
                 URL: https://issues.apache.org/jira/browse/HIVE-15205
             Project: Hive
          Issue Type: Sub-task
          Components: repl
            Reporter: Vaibhav Gumashta
            Assignee: Vaibhav Gumashta


The current bootstrap code generates dump metadata during semantic analysis which breaks security and task/work abstraction. It also uses existing classes (from Export/Import world) for code reuse purpose, but as a result ends up dealing with a lot if-then-elses. It makes sense to have a cleaner abstraction which uses ReplDumpTask and ReplDumpWork (to configure the Task). Also perhaps worth evaluating ReplLoadTask/ReplLoadWork for load side.
