A Machine Learning Model learns from data. As you get new incremental data, the Machine Learning model needs to be upgraded. A Machine Learning Model factory ensures that as you have deployed model in production, continuous learning is also happening on incremental new data ingested in the Production environment. As deployed ML Model's performance decays, a new trained and serialized model needs to be deployed. An A/B test between the deployed model and the newly trained model can score them to evaluate the performance of the deployed model versus the incrementally trained model. In order to build a Machine Learning Model factory, we have to establish a robust road to production, first. The foundational framework is first to establish three environments: DEV, TEST and PROD. 1- DEV - A development environment where the Data Scientists have their own data puddle in order to perform data exploration, profile the data, develop the machine learning features from the data, build the model, train and test it on the limited subset and then commit to git to transport the code to the next stages. For the purpose of scaling and tuning the learning of the Machine Learning model, we establish a DEV Validation environment, where the model learning is scaled with as much historical data as possible and tuned. 2- TEST - The TEST environment is a pre-production environment where we running the machine learning models through integration tests and readying the move of the Machine Learning model to production in two branches: 2a - model deployment: where the trained serialized Machine Learning model is deployed in the production environment 2b - continuous training: where the Machine Learning model is going through continuous training on incremental data 3- PROD - The Production environment is where live data is ingested. In the production environment a deployment server is hosting the serialized trained model. The deployed model exposes a REST api to deliver predictions on live data queries. The ML model code is running in production ingesting incremental live data and getting continuously trained. The deployed model and the continuous training model performances are measured. If the deployed model is showing decay in prediction performance, then it is switched with a newer serialized version of the continuous training model. The model performance measure can be tracked by closing the loop with the users feedback and tracking True Positive, False Positive, True Negative and False Negative.

Interacting with Hadoop HDFS using Python codes This post will go through the following: Introducing python “subprocess” module Running HDFS commands with Python Examples of HDFS commands from Python 1-Introducing python “subprocess” module The Python “subprocess” module allows us to: spawn new Unix processes connect to their input/output/error pipes obtain their return codes To run UNIX commands we need to create a subprocess that runs the command. The recommended approach to invoking subprocesses is to use the convenience functions for all use cases they can handle. Or we can use the underlying Popen interface can be used directly. 2-Running HDFS commands with Python We will create a Python function called run_cmd that will effectively allow us to run any unix or linux commands or in our case hdfs dfs commands as linux pipe capturing stdout and stderr and piping the input as list of arguments of the elements of the native unix or HDFS command. It is passed as a Python list rather than a string of characters as you don't have to parse or escape characters. # import the python subprocess module import subprocess def run_cmd(args_list): """ run linux commands """ # import subprocess print('Running system command: {0}'.format(' '.join(args_list))) proc = subprocess.Popen(args_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE) s_output, s_err = proc.communicate() s_return = proc.returncode return s_return, s_output, s_err 3-Examples of HDFS commands from Python Run Hadoop ls command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-ls', 'hdfs_file_path']) lines = out.split('\n') Run Hadoop get command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-get', 'hdfs_file_path', 'local_path']) Run Hadoop put command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-put', 'local_file', 'hdfs_file_path']) Run Hadoop copyFromLocal command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-copyFromLocal', 'local_file', 'hdfs_file_path']) Run Hadoop copyToLocal command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-copyToLocal', 'hdfs_file_path', 'local_file']) hdfs dfs -rm -skipTrash /path/to/file/you/want/to/remove/permanently Run Hadoop remove file command in Python (ret, out, err)= run_cmd(['hdfs', 'dfs', '-rm', 'hdfs_file_path']) (ret, out, err)= run_cmd(['hdfs', 'dfs', '-rm', '-skipTrash', 'hdfs_file_path']) rm -r HDFS Command to remove the entire directory and all of its content from HDFS. Usage: hdfs dfs -rm -r <path> (ret, out, err)= run_cmd(['hdfs', 'dfs', '-rm', '-r', 'hdfs_file_path']) (ret, out, err)= run_cmd(['hdfs', 'dfs', '-rm', '-r', '-skipTrash', 'hdfs_file_path']) Check if a file exist in HDFS Usage: hadoop fs -test -[defsz] URI Options: -d: f the path is a directory, return 0. -e: if the path exists, return 0. -f: if the path is a file, return 0. -s: if the path is not empty, return 0. -z: if the file is zero length, return 0. Example: hadoop fs -test -e filename hdfs_file_path = '/tmpo' cmd = ['hdfs', 'dfs', '-test', '-e', hdfs_file_path] ret, out, err = run_cmd(cmd) print(ret, out, err) if ret: print('file does not exist') These simple but very powerful lines of code allow to interact with HDFS in a programmatic way and can be easily scheduled as part of schedule cron jobs. ...

Installing and Exploring Spark 2.0 with Jupyter Notebook and Anaconda Python in your laptop 1-Objective 2-Installing Anaconda Python 3-Checking Python Install 4-Installing Spark 5-Checking Spark Install 6-Launching Jupyter Notebook with PySpark 2.0.2 7-Exploring PySpark 2.0.2 a.Spark Session b.Read CSV i.Spark 2.0 and Spark 1.6 ii.Pandas c.Pandas DataFrames, Spark DataSets, DataFrames and RDDs d.Machine Learning Pipeline i.SciKit Learn ii.Spark MLLib, ML 8-Conclusion 1-Objective It is often useful to have python with the Jupyter notebook installed on your laptop in order to quickly develop and test some code ideas or to explore some data. Adding the ability to combine Apache Spark to this will also allow you to prototype ideas and exploratory data pipelines before hitting a Hadoop cluster and paying for Amazon Web Services. We leverage the power of the Python ecosystem with libraries such as Numpy (scientific computing library of high-level mathematical functions to operate on arrays and matrices), SciPy (SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation), Pandas (high performance data structure and data analysis library to build complex data transformation flows), Scikit-Learn (library that implements a range of machine learning, preprocessing, cross-validation and visualization algorithms), NLTK (Natural Language Tool Kit to process text data, libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, wrappers for industrial-strength NLP libraries)… We also leverage the strengths of Spark including Spark-SQL, Spark-MLLib or ML. 2-Installing Anaconda Python We install Continuum’s Anaconda distribution by downloading the install script from the Continuum website. https://www.continuum.io/downloads The advantage of the Anaconda distribution is that lot of the essential python packages comes in bundled. You do not have to struggle with all the dependencies synchronization. We will use the following commands to download the install script. The command is to install Python version 3.5 HW12256:~ usr000$ wget http://repo.continuum.io/archive/Anaconda3-4.2.0-Linux-x86_64.sh If you wish to install Python 2.7, the following download is recommended. HW12256:~ usr000$ wget http://repo.continuum.io/archive/Anaconda2-4.2.0-Linux-x86_64.sh Accordingly, in the terminal, issue the following bash command to launch the install. Python 3.5 version HW12256:~ usr000$ bash Anaconda3-4.2.0-Linux-x86_64.sh Python 2.7 version HW12256:~ usr000$ bash Anaconda2-4.2.0-Linux-x86_64.sh In the following steps, we are using Python 3.5 as the base environment. 3-Checking Python Install   In order to check the Python install, we issue the following commands in the terminal.

In the case of the machine learning pipeline, we will contract Spark MLLib or ML with Scikit Learn.   a.Spark Session Spark 2.0 introduces SparkSession. SparkSession is the single entry point for interacting with Spark functionality. It replaces and encapsulates the SQLContext, HiveContext and StreamingContext for a more unified access to the DataFrame and Dataset APIs. The SQLContext, HiveContext and StreamingContext still exist under the hood in Spark 2.0 for continuity purpose with the Spark legacy code. The Spark session has to be created when using spark-submit command. An example on how to do that: from pyspark.sql import SparkSession from pyspark import SparkContext from pyspark import SparkConf # from pyspark.sql import SQLContext spark = SparkSession\ .builder\ .appName("example-spark")\ .config("spark.sql.crossJoin.enabled","true")\ .getOrCreate()sc = SparkContext() # sqlContext = SQLContext(sc) When typing ‘pyspark’ at the terminal, python automatically creates the spark context sc. A SparkSession is automatically generated and available as 'spark'. Application name can be accessed using SparkContext. spark.sparkContext.appName# Configuration is accessible using RuntimeConfig:from py4j.protocol import Py4JErrortry: spark.conf.get("some.conf")except Py4JError as e: pass The following code outline the available spark context sc as well as the new spark session under the name "spark" which includes the previous sqlContext, HiveContext, StreamingContext under one unified single entry point. sqlContext, HiveContext, StreamingContext still exist to ensure continuity with legacy code in Spark.
