> In case if there is no delegation token put into token file, this [line|https://github.com/apache/hive/blob/master/jdbc/src/java/org/apache/hive/jdbc/HiveConnection.java#L777]
will cause a NullPointerException which is not handled and the user is not notified in any
way.
> To cause NPE the use case is to have an Oozie Sqoop import to Hive in a kerberized cluster.
Oozie puts the delegation token into the token file with id: *HIVE_DELEGATION_TOKEN_hiveserver2ClientToken*.
So with id *hive* it is not working. However, fallback code uses the key which Oozie provides
[this|https://github.com/apache/hive/blob/master/jdbc/src/java/org/apache/hive/jdbc/HiveConnection.java#L784]
way.
> I suggest to have warning message to user that key with id *hive* cannot be used and
falling back to get delegation token from the session.
> I am creating the patch.
