Vaibhav Gumashta updated HIVE-15205:
------------------------------------
Description:
-- 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.
-- Also consider including here: avoid deserializing notification and
serializing again during repl dump. The notification should contain all info
already (if not, fix it)
