Use the JDBC interpreter to access Hive

The %jdbc interpreter supports access to Apache Hive data. The interpreter connects to Hive via Thrift.

If you want Hive queries to run under the user ID originating the query, see "Configuring User Impersonation for Access to Hive" in this guide.

To use the JDBC interpreter to access Hive:

1. Add the following directive at the start of a paragraph:

   %jdbc(hive)

2. Next, add the query that accesses Hive.

Here is a sample paragraph:

%jdbc(hive)
SELECT * FROM db_name;

If you receive an error, you might need to complete the following additional steps:

1. Copy Hive jar files to /opt/cloudera/parcels/<version>/lib/zeppelin/interpreter/<name_of_interpreter> (or create a soft link).

   For example, /opt/cloudera/parcels/<version>/lib/zeppelin/interpreter/livy/

2. In the Zeppelin UI, navigate to the %jdbc section of the Interpreter page.
3. Click edit, then add a hive.proxy.user.property property and set its value tohive.server2.proxy.user.
4. Click Save, then click restart to restart the JDBC interpreter.
