anishek updated HIVE-18467:
---------------------------
Description:
A complete hive warehouse might be required to replicate to a DR site for
certain use cases and rather than allowing only a database name in the REPL
DUMP commands, we should allow dumping of all databases using the "*" option as
in
_REPL DUMP *_
On the repl load side there will not be an option to specify the database name
when loading from a location used to dump multiple databases, hence only
_REPL LOAD FROM [location]_ would be supported when dumping via _REPL DUMP *_
Additionally, incremental dumps will go through all events across databases in
a warehouse and hence CREATE / DROP Database events have to be serialized
correctly to allow repl load to create them correctly.
