------------------------------------
Summary: HMS APIs to be enhanced for metadata replication
Key: HIVE-26012
URL: https://issues.apache.org/jira/browse/HIVE-26012
Project: Hive
Issue Type: Improvement
Components: Metastore
Affects Versions: 3.1.0
Reporter: Naveen Gangam
HMS currently has APIs like these that automatically create/delete the
directories on the associated DFS.
[create/drop]_database
[create/drop]_table*
[add/append/drop]_partition*
This is expected and should be this way when query processors use this APIs.
However, when tools that replicate hive metadata use this APIs on the target
cluster, creating these dirs on target side which cause the replication of
DFS-snapshots to fail.
So we if provide an option to bypass this creation of dirs, dfs replications
will be smoother. In the future we will need to restrict users that can use
these APIs. So we will have some sort of an authorization policy.
