Hue, JDBC and my JAR file

Dear all,

I am struggeling with some problems regarding a JAR file and HUE. 

 

As outlined here it's possible to integrate a database in HUE. 

So I try to do this as well. Therefor I downloaded a JAR file and try to integrate this in HUE. 

 

So I added a notebook and my code looks like the following lines

 

[notebook]
show_notebooks=true
[[interpreters]]
[[[hive]]]
name = Hive
interface = hiveserver2
[[[jdbc]]]
name=JDBC
interface=jdbc
options='{"url": "jdbc:drill:zk=r2c00.pmd.local:2181,r2c01.pmd.local:2181,r2c02.pmd.local:2181/drill/pacluster;schema=pacs2","driver": "org.apache.drill.jdbc.Driver","user": "admin","password": "admin"}'

 

I see my notebook called JDBC

If I want to execute the following code 

select * from pacs2.pacs2.campaign limit 10

 

I get the following error

 

An error occurred while calling z:java.sql.DriverManager.getConnection. : java.sql.SQLException: No suitable driver found for jdbc:drill:zk=r2c00.pmd.local:2181,r2c01.pmd.local:2181,r2c02.pmd.local:2181/drill/pacluster;schema=pacs2 at java.sql.DriverManager.getConnection(DriverManager.java:689) at java.sql.DriverManager.getConnection(DriverManager.java:247) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at py4j.reflection.MethodInvoker.invoke(MethodInvoker.java:231) at py4j.reflection.ReflectionEngine.invoke(ReflectionEngine.java:379) at py4j.Gateway.invoke(Gateway.java:259) at py4j.commands.AbstractCommand.invokeMethod(AbstractCommand.java:133) at py4j.commands.CallCommand.execute(CallCommand.java:79) at py4j.GatewayConnection.run(GatewayConnection.java:207) at java.lang.Thread.run(Thread.java:745)

 

Obviously HUE is not possible to find the driver. Surprisingly if I try to connect to the database via SQuirrel SQL it's no problem.

 

 

So my key question is where I have to locate the JDBC jar file? Is there a specific location for this file?

 

I am using HUE 3.11 and Cloudera CDH 5.9.0.

 

Thanks for all your help!
