Denes Bodo created HIVE-21507: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
