[ZEPPELIN-2753] Basic Implementation of IPython Interpreter
### What is this PR for? This is the first step for implement IPython Interpreter in Zeppelin. I just use the jupyter_client to create and manage the ipython kernel. We don't need to care about python compilation and execution, all the things are delegated to ipython kernel. Ideally all the features of ipython should be available in Zeppelin as well. For now, user can use %python.ipython for IPython Interpreter. And if ipython is available, the default python interpreter will use ipython. But user can still set `zeppelin.python.useIPython` as false to enforce to use the old implementation of python interpreter. Main features: * IPython interpreter support ** All the ipython features are available, including visualization, ipython magics. * ZeppelinContext support * Streaming output support * Support Ipython in PySpark Regarding the visualization, ideally all the visualization libraries work in jupyter should also work here. In unit test, I only verify the following 3 popular visualization library. could add more later. * matplotlib * bokeh * ggplot ### What type of PR is it?

[ZEPPELIN-2766] Make online resources url configurable at compile time
### What is this PR for? At compile time Zeppelin is downloading several external resources. I want to be able to provide alternative URLs to compile when internet is not available(i.e. behind corporate proxy). ### What type of PR is it? [Improvement] ### What is the Jira issue?

[ZEPPELIN-2298] Remove -Ppyspark build profile
### What is this PR for? Currently users who build Zeppelin from source need to include `-Ppyspark` to use `%pyspark` with embedded local Spark. But it's quite inconvenient to write this build profile every time we build i think. So I removed `-Ppyspark` and make pyspark related libraries automatically downloaded when we build Zeppelin. ### What type of PR is it? Improvement ### Todos * [x] - remove the rest of `-Ppyspark` build profile in `dev/create_release.sh`, `dev/publish_release.sh`, and `docs/install/build.md` after getting feedback ### What is the Jira issue? [ZEPPELIN-2298](https://issues.apache.org/jira/browse/ZEPPELIN-2298) ### How should this be tested? 1. Apply this patch 2. Build source with below command ``` mvn clean package -DskipTests -pl 'zeppelin-interpreter, zeppelin-zengine, zeppelin-server, zeppelin-display, spark, spark-dependencies' ``` Aftr this step, there will be `pyspark` dir under `ZEPPELIN_HOME/interpreter/spark`. Before this PR, only `dep` dir and `zeppelin-spark_2.10-0.8.0-SNAPSHOT.jar` is generated without `-Ppyspark` build profile. 4. Restart Zeppelin. To make sure, run any python code e.g. ``` %pyspark print("Hello "+z.input("name")) ``` It should be run successfully without any error ### Screenshots (if appropriate) tl;dr Without `-Ppyspark` profile - Before <img width="856" alt="screen shot 2017-04-02 at 2 50 57 pm" src="https://cloud.githubusercontent.com/assets/10060731/24584778/0e8ec6b0-17b4-11e7-9f0d-f2599fd7bd63.png"> - After <img width="893" alt="screen shot 2017-04-02 at 2 28 21 pm" src="https://cloud.githubusercontent.com/assets/10060731/24584779/10b7ed68-17b4-11e7-90d4-aa95eb9bba2d.png"> ### Questions: * Does the licenses files need update? no * Is there breaking changes for older versions? no * Does this needs documentation? no I want to include `SparkR` by default(= remove `-PsparkR` build profile) like this as a next step. I want to ask how Zeppelin community think about this.

Rewrite PythonInterpreter.
### What is this PR for? I've been testing the python interpreter and I found at least 4 major issues in the current python interpreter. 1. not working streaming output. - https://issues.apache.org/jira/browse/ZEPPELIN-2225 2. printed "..." when there is indent in the python code. - https://issues.apache.org/jira/browse/ZEPPELIN-1929 3. very slow output of matplotlib - https://issues.apache.org/jira/browse/ZEPPELIN-1894 - https://issues.apache.org/jira/browse/ZEPPELIN-1360 4. Unexpected output of matplotlib. - https://issues.apache.org/jira/browse/ZEPPELIN-2107 so I changed python interpreter to use py4j based on pyspark interpreter and would be fixed above issues. and I am going to recreate conda, docker for python interpreter ASAP. ### What type of PR is it?

ZEPPELIN-1345 - Create a custom matplotlib backend that natively supports inline plotting in a python interpreter cell
### What is this PR for? This PR is the first of two major steps needed to improve matplotlib integration in Zeppelin (ZEPPELIN-1344). The latter, which is a plotting backend with fully interactive tools enabled, will be done afterwards in a separate PR. This PR specifically for automatically displaying output from calls to matplotlib plotting functions inline with each paragraph. Thanks to the addition of post-execute hooks (ZEPPELIN-1423), there is no need to call any `show()` function to display an inline plot, just like in Jupyter. ### What type of PR is it? Improvement ### Todos The main code has been written and anyone who reads this is encouraged to test it, but there are a few minor todos: - [x] - Add unit tests - [x] - Add documentation - [x] - Add screenshot showing iterative plotting with angular mode ### What is the Jira issue? [ZEPPELIN-1345](https://issues.apache.org/jira/browse/ZEPPELIN-1345) ### How should this be tested? In a pyspark or python paragraph, enter and run ``` python import matplotlib.pyplot as plt plt.plot([1, 2, 3]) ``` The plot should be displayed automatically without calling any `show()` function whatsoever. A special method called `configure_mpl()` can also be used to modify the inline plotting behavior. For example, ``` python z.configure_mpl(close=False, angular=True) plt.plot([1, 2, 3]) ``` allows for iterative updates to the plot provided you have PY4J installed for your python installation (which of course is always the case if you use pypsark). To clarify, this feature only currently works with pyspark (not python as there are no `angularBind()` and `angularUnbind()` methods yet). Doing something like: ``` plt.plot([3, 2, 1]) ``` will update the plot that was generated by the previous paragraph by leveraging Zeppelin's Angular Display System. However, by setting `close=False`, matplotlib will no longer automatically close figures so it is now up to the user to explicitly close each figure instance they create. There's quite a bit more options for `z.configure_mpl()`, but I will save that discussion for the documentation. ### Screenshots (if appropriate)  ### Questions: - Does the licenses files need update? No - Is there breaking changes for older versions? No - Does this needs documentation?

[ZEPPELIN-986] Create publish release script
### What is this PR for? This PR is to automate release publish to maven repository. We used to use maven-deploy-plugin and maven-release-plugin for release but somehow it didn't work well with Zeppelin so 0.5.5 and 0.5.6 haven't been published to maven repository. Publishing release to maven repository will eventually help zeppelin to reduce binary package size by leading users to use Dynamic interpreter loading(#908). Originally below modules were skipped for maven release - all interpreters(except spark) - zeppelin-display - zeppelin-server - zeppelin-distribution on the other hand this pr will skip only: - zeppelin-distribution ### What type of PR is it? Infra ### Todos - [x] Include SparkR/R interpreter in release - [x] Create common_release.sh to remove build configuration duplication - [x] Check curl networking failure ### What is the Jira issue? [ZEPPELIN-986](https://issues.apache.org/jira/browse/ZEPPELIN-986) ### Questions: * Does the licenses files need update? No * Is there breaking changes for older versions? No * Does this needs documentation? Yes, https://cwiki.apache.org/confluence/display/ZEPPELIN/Preparing+Zeppelin+Release will be updated accordingly once this pr is merged.

[ZEPPELIN-502] Python interpreter group
### What is this PR for? Adding a python 2 &3 interpreter. It's a basic implementation (no py4j for example), with a java ProcessBuilder object used to instantiate a python REPL. The interpreter doesn't bring it own python binary but uses the python specified by python.path configutation. Thus, you can still use your specific installed python modules (scikit-learn, matplotlib...) and the interpreter is able to work with python 2 & 3 without change. I had a python helper function (zeppelin_show() ) to easily display matplotlib graph as SVG. ### What type of PR is it? [Feature] ### Todos * [x] - Code review * [x] - Improve bootstrap.py : choose available helper functions and their names * [x] - Unit / IT tests ? * [x] documentation updates needed, that AhyoungRyu pointed out * [X] LICENSE needs to be updated to include all non-apache licensed dependencies (i.e AFAIK Py4j is BSD ) in bin-license * [x] double-check that code formatting conforms project style guide * [x] the branch need to be rebased on latest master. ### What is the Jira issue? [ZEPPELIN-502](https://issues.apache.org/jira/browse/ZEPPELIN-502?jql=project%20%3D%20ZEPPELIN%20AND%20text%20~%20%22python%22) ### How should this be tested? 1. In interpreter screen, in Python section, specify in python.path the python binary you want to use 2. In a paragraph, you can use the interpreter with **_%python_**. Calling help() will describe you the interpreter functionnalities. 3. Install py4j (pip install py4j) if you want to use input form ### Screenshots     ### Questions: * Does the licenses files need update? Yes, only bin-license (py4j) * Is there breaking changes for older versions? No * Does this needs documentation? Yes Author: Hervé RIVIERE <hriviere@users.noreply.github.com> Closes #869 from hriviere/PR_interpreter_python and squashes the following commits: |
