HonglunChen commented on SPARK-34632:
-------------------------------------
The main purpose is to get the username from
org.apache.hadoop.hive.ql.session.SessionState and then Hive use the username
to do authentication. Please see
[https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/security/SessionStateUserAuthenticator.java#L49].
My use case is at the line 49 in the
[SessionStateUserAuthenticator.java|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/security/SessionStateUserAuthenticator.java#L49].
Now 'sessionState.getUserName()' will return null, thus Hive can not do
authentication.
The SessionSate is created in HiveClientImpl.scala without setting up username:
val state = new SessionState(hiveConf)
So, all I need is to set the current user in SessionState, which like this:
val state = new SessionState(hiveConf,username)
I don't know if you know what I mean.
> Can we create 'SessionState' with a username in 'HiveClientImpl'
