### What is this PR for?
In ZEPPELIN-1607, I'd like refactor livy interpreter to scoped mode by default, this require username when open this interpreter. So I propose to pass username when creating interpreter through thrift.

* This is one compilation issue (`PythonDockerInterpreterTest.java`) in the existing master branch, I also fix it here.

Contributing to Apache Zeppelin ( Code )

NOTE : Apache Zeppelin is an Apache2 License Software. Any contributions to Zeppelin (Source code, Documents, Image, Website) means you agree with license all your contributions as Apache2 License.

Setting up

Here are some tools you will need to build and test Zeppelin.

Software Configuration Management ( SCM )

Since Zeppelin uses Git for it's SCM system, you need git client installed in your development machine.

Integrated Development Environment ( IDE )

You are free to use whatever IDE you prefer, or your favorite command line editor.

Build Tools

To build the code, install

Oracle Java 7
Apache Maven

Getting the source code

First of all, you need Zeppelin source code. The official location of Zeppelin is http://git.apache.org/zeppelin.git.

git access

Get the source code on your development machine using git.

git clone git://git.apache.org/zeppelin.git zeppelin

You may also want to develop against a specific branch. For example, for branch-0.5.6

git clone -b branch-0.5.6 git://git.apache.org/zeppelin.git zeppelin

Apache Zeppelin follows Fork & Pull as a source control workflow. If you want to not only build Zeppelin but also make any changes, then you need to fork Zeppelin github mirror repository and make a pull request.

Build

mvn install

To skip test

mvn install -DskipTests

To build with specific spark / hadoop version

mvn install -Dspark.version=x.x.x -Dhadoop.version=x.x.x

For the further

Run Zeppelin server in development mode

cd zeppelin-server
HADOOP_HOME=YOUR_HADOOP_HOME JAVA_HOME=YOUR_JAVA_HOME mvn exec:java -Dexec.mainClass="org.apache.zeppelin.server.ZeppelinServer" -Dexec.args=""

Note: Make sure you first run mvn clean install -DskipTests on your zeppelin root directory, otherwise your server build will fail to find the required dependencies in the local repro.

or use daemon script

bin/zeppelin-daemon start

Server will be run on http://localhost:8080.

Generating Thrift Code

Some portions of the Zeppelin code are generated by Thrift. For most Zeppelin changes, you don't need to worry about this. But if you modify any of the Thrift IDL files (e.g. zeppelin-interpreter/src/main/thrift/*.thrift), then you also need to regenerate these files and submit their updated version as part of your patch.

To regenerate the code, install thrift-0.9.2 and then run the following command to generate thrift code.

cd <zeppelin_home>/zeppelin-interpreter/src/main/thrift
./genthrift.sh

Where to Start

You can find issues for beginner & newbie
