Submarine Interpreter for Apache Zeppelin
Hadoop Submarine is the latest machine learning framework subproject in the Hadoop 3.1 release. It allows Hadoop to support Tensorflow, MXNet, Caffe, Spark, etc. A variety of deep learning frameworks provide a full-featured system framework for machine learning algorithm development, distributed model training, model management, and model publishing, combined with hadoop's intrinsic data storage and data processing capabilities to enable data scientists to Good mining and the value of the data.
A deep learning algorithm project requires data acquisition, data processing, data cleaning, interactive visual programming adjustment parameters, algorithm testing, algorithm publishing, algorithm job scheduling, offline model training, model online services and many other processes and processes. Zeppelin is a web-based notebook that supports interactive data analysis. You can use SQL, Scala, Python, etc. to make data-driven, interactive, collaborative documents.
You can use the more than 20 interpreters in zeppelin (for example: spark, hive, Cassandra, Elasticsearch, HBase, etc.) to collect data, clean data, feature extraction, etc. in the data in Hadoop before completing the machine learning model training. The data preprocessing process.
By integrating submarine in zeppelin, we use zeppelin's data discovery, data analysis and data visualization and collaboration capabilities to visualize the results of algorithm development and parameter adjustment during machine learning model training.
Architecture
As shown in the figure above, how the Submarine develops and models the machine learning algorithms through Zeppelin is explained from the system architecture.
After installing and deploying Hadoop 3.1+ and Zeppelin, submarine will create a fully separate Zeppelin Submarine interpreter Docker container for each user in YARN. This container contains the development and runtime environment for Tensorflow. Zeppelin Server connects to the Zeppelin Submarine interpreter Docker container in YARN. allows algorithmic engineers to perform algorithm development and data visualization in Tensorflow's stand-alone environment in Zeppelin Notebook.
After the algorithm is developed, the algorithm engineer can submit the algorithm directly to the YARN in offline transfer training in Zeppelin, real-time demonstration of model training with Submarine's TensorBoard for each algorithm engineer.
You can not only complete the model training of the algorithm, but you can also use the more than twenty interpreters in Zeppelin. Complete the data preprocessing of the model, For example, you can perform data extraction, filtering, and feature extraction through the Spark interpreter in Zeppelin in the Algorithm Note.
In the future, you can also use Zeppelin's upcoming Workflow workflow orchestration service. You can complete Spark, Hive data processing and Tensorflow model training in one Note. It is organized into a workflow through visualization, etc., and the scheduling of jobs is performed in the production environment.
Overview
As shown in the figure above, from the internal implementation, how Submarine combines Zeppelin's machine learning algorithm development and model training.
The algorithm engineer created a Tensorflow notebook (left image) in Zeppelin by using Submarine interpreter.
It is important to note that you need to complete the development of the entire algorithm in a Note.
You can use Spark for data preprocessing in some of the paragraphs in Note.
Use Python for algorithm development and debugging of Tensorflow in other paragraphs of notebook, Submarine creates a Zeppelin Submarine Interpreter Docker Container for you in YARN, which contains the following features and services:
- Shell Command line tool：Allows you to view the system environment in the Zeppelin Submarine Interpreter Docker Container, Install the extension tools you need or the Python dependencies.
- Kerberos lib：Allows you to perform kerberos authentication and access to Hadoop clusters with Kerberos authentication enabled.
- Tensorflow environment：Allows you to develop tensorflow algorithm code.
- Python environment：Allows you to develop tensorflow code.
- Complete a complete algorithm development with a Note in Zeppelin. If this algorithm contains multiple modules, You can write different algorithm modules in multiple paragraphs in Note. The title of each paragraph is the name of the algorithm module. The content of the paragraph is the code content of this algorithm module.
HDFS Client：Zeppelin Submarine Interpreter will automatically submit the algorithm code you wrote in Note to HDFS.
Submarine interpreter Docker Image It is Submarine that provides you with an image file that supports Tensorflow (CPU and GPU versions). And installed the algorithm library commonly used by Python. You can also install other development dependencies you need on top of the base image provided by Submarine.
- When you complete the development of the algorithm module, You can do this by creating a new paragraph in Note and typing
%submarine dashboard. Zeppelin will create a Submarine Dashboard. The machine learning algorithm written in this Note can be submitted to YARN as a JOB by selecting theJOB RUNcommand option in the Control Panel. Create a Tensorflow Model Training Docker Container, The container contains the following sections:
- Tensorflow environment
HDFS Client Will automatically download the algorithm file Mount from HDFS into the container for distributed model training. Mount the algorithm file to the Work Dir path of the container.
Submarine Tensorflow Docker Image There is Submarine that provides you with an image file that supports Tensorflow (CPU and GPU versions). And installed the algorithm library commonly used by Python.

JOB RUNwill display the parameter input interface for submitting JOB.
| Name | Description |
|---|---|
| Checkpoint Path/td> | Submarine sets up a separate Checkpoint path for each user's Note for Tensorflow training. Saved the training data for this Note history, Used to train the output of model data, Tensorboard uses the data in this path for model presentation. Users cannot modify it. For example: `hdfs://cluster1/...` , The environment variable name for Checkpoint Path is `%checkpoint_path%`, You can use `%checkpoint_path%` instead of the input value in Data Path in `PS Launch Cmd` and `Worker Launch Cmd`. |
| Input Path | The user specifies the data data directory of the Tensorflow algorithm. Only HDFS-enabled directories are supported. The environment variable name for Data Path is `%input_path%`, You can use `%input_path%` instead of the input value in Data Path in `PS Launch Cmd` and `Worker Launch Cmd`. |
