---------------------------------
Summary: Hive swallows NPE if no delegation token found
Key: HIVE-21507
URL: https://issues.apache.org/jira/browse/HIVE-21507
Project: Hive
Issue Type: Bug
Components: JDBC
Affects Versions: 3.1.1
Reporter: Denes Bodo
Assignee: Denes Bodo
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.
