------------------------------
Summary: support whole warehouse dump / load + create/drop
database events
Key: HIVE-18467
URL: https://issues.apache.org/jira/browse/HIVE-18467
Project: Hive
Issue Type: Bug
Affects Versions: 3.0.0
Reporter: anishek
Assignee: anishek
Fix For: 3.0.0
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.
