Get Help In Big Data Map-Reduce

In a MapReduce program, Map() and Reduce() are two functions. The Map function performs actions like filtering, grouping and sorting. While Reduce function aggregates and summarizes the result produced by map function. The result generated by the Map function is a key value pair (K, V) which acts as the input for Reduce function. Basic Steps To Perform Map Reduce: Input Splits: It is a fixed-size pieces called input splits Input split is a chunk of the input that is consumed by a single map Mapping In this phase data in each split is passed to a mapping function to produce output values. In our example, a job of mapping phase is to count a number of occurrences of each word from input splits (more details about input-split is given below) and prepare a list in the form of <word, frequency> Shuffling This phase consumes the output of Mapping phase. Its task is to consolidate the relevant records from Mapping phase output. In our example, the same words are clubed together along with their respective frequency. Reducing In this phase, output values from the Shuffling phase are aggregated. This phase combines values from Shuffling phase and returns a single output value. In short, this phase summarizes the complete dataset.

Perform Map Reduce For Integer Number

Problem statement: You are given a large number of files containing positive integers. Design the MapReduce process to compute the number of even integers across all files. Before answering the question we will creating MapReduce job using positive integers with, <key, value> Using MapReduce, determine how many odd and even numbers of jobs in positive integer jobs.

Get Help In Big Data Hadoop/HDFS The Hadoop Distributed File System (HDFS) is the primary data storage system used by Hadoop applications. HDFS employs a NameNode and DataNode architecture to implement a distributed file system that provides high-performance access to data across highly scalable Hadoop clusters. Here you can get good quality code from our expert. Our expert focus to deliver code without any Plagiarism and within your due.

Big Data can be characterized by:

  • Volume - the amount and scale of data

  • Velocity - the speed at which data travels in and out

  • Variety - the range and complexity of data types, structures, and sources


  • Financial markets - 7 billion shares change hands every day in the U.S. markets

  • Google, Twitter, GPS data, Facebook, YouTube, etc.

MapReduce is a framework for processing large-scale data using parallel and distributed computing technologies with a large number of computers. Apache Hadoop is an open-source implementation of MapReduce. Big Data Analytics using Spark SQL PySpark SQL is a module in Spark which integrates relational processing with Spark's functional programming API. We can extract the data by using an SQL query language. We can use the queries same as the SQL language. If you have basic understanding related to RDBMS, SQL, and Data Analytics then you can easily work with this. Feature of PySpark SQL: Consistence Data Access, Incorporation with Spark, Standard Connectivity, User-Defined Functions, Hive Compatibility

Big Data Sample Paper

Abstract In artificial intelligence, machine learning is a method of acquiring knowledge that may be used to make intelligent judgments. There are many benefits to using big data for scientific research and value generation. This report introduces machine learning methods, Big Data technology, and machine learning applications in Big Data. There is a discussion of the challenges of machine learning applications with big data. Also highlighted are several new machine learning methodologies and technological advancements in Big Data. The Spark Python API (PySpark) exposes the Spark programming model to Python. Apache® Spark™ is an open source and is one of the most popular Big Data frameworks for scaling up your tasks in a cluster. It was developed to utilize distributed, in-memory data structures to improve data processing speeds. Apache Spark! The top technology companies like Google, Facebook, Netflix, Airbnb, Amazon, NASA, and more are all using Spark to solve their big data problems!


Machine learning is an important area of artificial intelligence. The goal of machine learning is to discover knowledge and make intelligent decisions. Machine learning algorithms can be classified into which are classified into supervised, unsupervised, and semi-supervised. When it comes to big data, scaling machine learning algorithms are needed (Chen and Zhang, 2014; Tarwani et al., 2015), Another classification of machine learning based on the output of the machine learning system includes classification, regression, clustering, and density estimation, etc. machine-learning approaches include decision tree learning, association rule learning, artificial neural networks, support vector machines (SVM), clustering, Bayesian networks, and genetic algorithms, etc

Load Data

from google.colab import drive

from pyspark.sql import SparkSession
spark = SparkSession.builder.appName('ml-bank').getOrCreate()
#reading the data and Printing the schema of main dataset
df ='/content/drive/MyDrive/UNSW-NB15_features.csv', header = True, inferSchema = True)

After preprocessing the data apply classifiers:

Binary Classifier

#Splitting the dataset 
train, test = df_1.randomSplit([0.7, 0.3], seed = 2018)
print("Training Dataset Count: " + str(train.count()))

Using Decision Tree Classifier

from import DecisionTreeClassifier
dt = DecisionTreeClassifier(featuresCol = 'features', labelCol = 'Label', maxDepth = 3)dtModel =

predictions = dtModel.transform(test) 'Label', 'rawPrediction', 'prediction', 'probability').show(10)


Multi Classifier

cat_col2 = [key for key in dict(df_2.dtypes)if dict(df_2.dtypes)[key] in ['object'] ] # Categorical Varible

num_col2 = list(df_2.select_dtypes(exclude=['object']).columns)
from import OneHotEncoderfrom import StringIndexer, VectorAssembler
from import StringIndexer, VectorAssembler

The procedure incorporates Category Indexing, One-Hot Encoding, and  VectorAssembler, a feature converter that merges many columns into a  vector column.
stages = []
for categoricalCol in cat_col2:
    stringIndexer = StringIndexer(inputCol = categoricalCol, outputCol = categoricalCol + 'Index')
    encoder = OneHotEncoder(inputCols=[stringIndexer.getOutputCol()], outputCols=[categoricalCol + "classVec"])
    stages += [stringIndexer, encoder]
label_stringIdx = StringIndexer(inputCol = 'attack_cat', outputCol = 'target')
stages += [label_stringIdx]

assemblerInputs = [c + "classVec" for c in cat_col2] + num_col2
assembler = VectorAssembler(inputCols=assemblerInputs, outputCol="features")
stages += [assembler]
