Riza Suminto commented on IMPALA-11963:
---------------------------------------

Yes! I forgot I already file that before.

So for HiveCatalog, Impala should double check to hive-site.xml.
What about HadoopCatalog? can we have multiple HadoopCatalog? It does look 
possible here, but maybe all are short-lived since they are not singleton like 
IcebergHiveCatalog:

> However, it would be nice to just simply add the property to the
