Use CLASSPATH value for creating JavaGateway and load JDBC driver class

[ShahabT]

Using this documentation I failed to connect Hue to my JDBC-compatible tool. When I investigated the source code I found that the CLASSPATH variable and the JDBC driver class name are not used anywhere in the code. So, my JDBC driver class is not loaded at all.
This PR fixes that and makes sure that the JDBC driver class is loaded.

Thanks!

And could you sign the agreement about contributing your code to the open source?

I am getting the same error as above. Is there a solution?

Hi,
Before launching Hue, you need to set the CLASSPATH environment variable. CLASSPATH should contain the full path of the JAR file of you JDBC driver class.
You can put something like bellow in you .bash_profile file, to make sure the variable is always set.

export CLASSPATH=/path/to/jdbc/driver.jar:$CLASSPATH

Hello, I think you should also update the Docker image to have it by default (at least define to avoid the error).

Here an example to use with Docker (I have downloaded jar on Docker host before):

docker run -tid -v ~/hue:/hue/desktop/conf  --name hue -p 8888:8888 
--add-host="hadoop:__IP__" 
-v $(pwd):/home/root 
-e CLASSPATH=/home/root/presto-jdbc-0.165.jar

to be clear, doesn't this mean the instructions provdied there that claim to work with 3.10 will not actually work until 3.12? Am i missing something? I'm on 3.11 and have got the classpath defined in the profile of the user that it's launching with, but no dice.
