[jira] [Created] (HIVE-25875) Support multiple authentication mechanisms simultaneously

 Summary: Support multiple authentication mechanisms simultaneously 
 Key: HIVE-25875
 URL: https://issues.apache.org/jira/browse/HIVE-25875
 Project: Hive
  Issue Type: Improvement
  Components: HiveServer2
Affects Versions: 3.1.0
Reporter: Naveen Gangam
Assignee: Naveen Gangam


Currently, HS2 supports a single form of auth on any given instance of 
HiveServer2. Hive should be able to support multiple auth mechanisms on a 
single instance especially with http transport. for example, LDAP and SAML.  In 
both cases, HS2 ends up with receiving an Authorization Header in the request. 
Similarly we could be able to support JWT support or other forms of boundary 
authentication that is done outside of Hive.

interestingly; the issue is not present:
* for a query not looking into the nested struct
* and in case the struct with the array is at the top level

{code}
select count(1) from t;
--explain
