+### Authentication Strategy for Hadoop Catalog
+
+The Hadoop catalog supports multi-level authentication to control access, 
allowing different strategies for the catalog, schema, and fileset. The 
priority of authentication strategies is as follows: catalog < schema < fileset.

Review Comment:
   > First. Is it a strategy? I have some concern about this term. They are 
different mechinisms for me instead of different straties.
   
   I will check the difference between them and choose a better one.
   
   > Second. The parent strategy will override the child or the parent property 
will override the children one. They are different.
   
   Let me think about it.
