ranger hive plugin not autocompleting databases and tables

New Contributor

Hi Team,

I have configured ranger and hive plugin using ambari. Following are my environment details,

HDP version = HDP-2.6.1.0

Hive version = 1.2.1000

Ranger version = 0.7.0

When i add a policy for hive, databases and tables not being autocompleted. I am getting following error in /var/log/ranger/admin/xa_portal.log.

From logs i found that it is due to hive jdbc version mismatching. https://issues.apache.org/jira/browse/HIVE-6050

Kindly help me to resolve this issue.

HI Th Kr,

i did following steps,

1. did backup of this folder /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive in ranger node.

cp /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hivebkp 1. copy hive jars from another node.

2. copied hive 1.2 jars and its dependencies jars into /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive folder

scp -r /usr/hdp/2.6.1.0-129/hive/lib/* root@hostname:/usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive/ where ip-172-31-4-145.us-east-2.compute.internal is ranger node. change ownership in ranger node.

3. Copied ranger plugin into /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive/ folder

cp ../hivebkp/ranger-hive-plugin-0.7.0.2.6.1.0-129.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive/

3. Changed ownership of this folder

chown -R ranger:ranger /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive

4. restarted ranger service and tested connection.

Note: this error not happened in hdp-2.6.2

I fixed this issue by changing ranger hive plugin classpath into hive-1.2 jdbc jar and its dependencies.

Best Regards,

Hey,

could give a little more information where you exactly changed the classpath?

We're stuck at the same problem.

Thanks!
