Top Hadoop Analytics Tools
1. Apache Spark
It is a popular open-source unified analytics engine for big data and machine learning. Apache Software Foundation developed Apache Spark for speeding up the Hadoop big data processing. It extends the Hadoop MapReduce model to effectively use it for more types of computations like interactive queries, stream processing, etc. Apache Spark enables batch, real-time, and advanced analytics over the Hadoop platform. Spark provides in-memory data processing for the developers and the data scientists
It has become the default execution engine for workloads such as batch processing, interactive queries, and streaming, etc.
Companies, including Netflix, Yahoo, eBay, and many more, have deployed Spark at a massive scale.
Features of Apache Spark:
- Speed: The powerful processing engine allows Apache Spark to quickly process the data in a large-scale. Spark has the ability to run applications in Hadoop clusters 100 times faster in memory and ten times faster on the disk.
- Ease of use: It can work with different data stores (such as OpenStack, HDFS, Cassandra) due to which it provides more flexibility than Hadoop. Spark supports both real-time and batch processing and provides high-level APIs in Java, Scala, Python, and R.
- Generality: It contains a stack of libraries, including MLlib for machine learning, SQL and DataFrames, GraphX, and Spark Streaming. We can combine these libraries in the same application.
- Runs Everywhere: Spark can run on Hadoop, Kubernetes, Apache Mesos, standalone, or in the cloud.

MapReduce is the heart of Hadoop. It is a software framework for writing applications that process large datasets in parallel across hundreds or thousands of nodes on the Hadoop cluster.
Hadoop divides the client’s MapReduce job into a number of independent tasks that run in parallel to give throughput. The MapReduce job is divided into map task and reduce task. Programmers generally write the entire business logic in the map task and specify light-weight processing like aggregation or summation on the reduce task. The MapReduce framework works in two phases- Map phase and the Reduce phase. The input to both the phases is the key-value pair.
Features of Hadoop MapReduce:
- Scalable: The MapReduce framework is scalable. Once we write a MapReduce program, we can easily expand it to work over a cluster having hundreds or even thousands of nodes.
- Fault-tolerance: It is highly fault-tolerant. It automatically recovers from failure.
3. Apache Impala
Apache Impala is an open-source tool that overcomes the slowness of Apache Hive. It is a native analytic database for Apache Hadoop. With Apache Impala, we can query data stored either in HDFS or HBase in real-time. Impala uses the same metadata, ODBC driver, SQL syntax, and user interface as Apache Hive, thus providing a familiar and uniformed platform for batch or real-time queries. We can integrate Apache Impala with Apache Hadoop and other leading BI tools to provide an inexpensive platform for analytics.
Features of Impala:
- Security: It is integrated with Hadoop security, and Kerberos thus ensures security.
- Expand the Hadoop user: With Impala, users using SQL queries or BI applications can interact with more data through metadata store from the source through analysis.
- Scalability: Impala scales linearly, even in multi-tenant environments.
- In-memory data processing: It supports in-memory data processing means that without any data movement, it easily accesses and analyzes the data stored on Hadoop DataNodes. Thus, it reduces cost due to reduced data movement, modeling, and storage.
- Faster Access: It provides faster access to data when compared to other SQL engines.
- Easy Integration: We can integrate Impala with BI tools like Tableau, Pentaho, Zoom data, etc.
- explore many more Impala features.
4. Apache Hive
Apache Hive is a java based data warehousing tool designed by Facebook for analyzing and processing large data. Hive uses HQL(Hive Query Language) similar to SQL that is transformed into MapReduce jobs for processing huge amounts of data. It provides support for developers and analytics to query and analyze big data with SQL like queries(HQL) without writing the complex MapReduce jobs.
Users can interact with the Apache Hive through the command line tool (Beeline shell) and JDBC driver. With Hive, one can analyze or query the vast amount of data stored in Hadoop HDFS without writing complex MapReduce jobs.
Features of Apache Hive:
- Hive supports client-application written in any language like Python, Java, PHP, Ruby, and C++.
- It generally uses RDBMS as metadata storage, which significantly reduces the time taken for the semantic check.
- Hive Partitioning and Bucketing improves query performance.
- Hive is fast, scalable, and extensible.
- It supports Online Analytical Processing and is an efficient ETL tool.
- It provides support for User Defined Function to support use cases that are not supported by Built-in functions.
Apache Mahout is an open-source framework that normally runs coupled with the Hadoop infrastructure at its background to manage large volumes of data. The name Mahout is derived from the Hindi word “Mahavat,” which means the rider of an elephant. As Apache Mahout runs algorithms on the top of the Hadoop framework, thus named as Mahout.
We can use Apache Mahout for implementing scalable machine learning algorithms on the top of Hadoop using the MapReduce paradigm. It is a library of the scalable machine learning algorithm. Previously, it uses the Apache Hadoop platform, but now it focuses more on Apache Spark. Apache Mahout is not restricted to the Hadoop based implementation; it can run algorithms in the standalone mode as well.
Apache Mahout implements popular machine learning algorithms such as Classification, Clustering, Recommendation, Collaborative filtering, etc.
Features of Mahout:

- Apache Mahout includes various MapReduce enabled clustering applications such as Canopy, Mean-Shift, K-means, fuzzy k-means.
- It also includes vectors and matrix libraries.
- Apache Mahout exposed various Classification algorithms such as Naive Bayes, Complementary Naive Bayes, and Random Forest.
Pig is an alternative approach to make MapReduce job easier. Yahoo developed Pig to provide ease in writing the MapReduce. Pig enables developers to use Pig Latin, which is a scripting language designed for pig framework that runs on Pig runtime. Pig Latin is SQL like commands that are converted to MapReduce program in the background by the compiler. It translate the Pig Latin into MapReduce program for performing large scale data processing in YARN.
It works by loading the commands and the data source. Then we perform various operations like sorting, filtering, joining, etc. At last, based on the requirement, the results are either dumped on the screen or stored back to the HDFS.
Features of Pig:
- Extensibility: Users can create their own function for performing specific purpose processing.
- Solving complex use cases: Pig is best suited for solving complex use cases that include multiple data processing having multiple imports and exports.
- Handles all kinds of data: Structured and Unstructured can be easily analyzed or processed using Pig.
- Optimization Opportunities: In Pig, the execution of the task gets automatically optimized by the task itself. Thus programmers need to focus on semantics rather than efficiency.
- It provides a platform for building data flow for ETL (Extract, Transform, and Load), processing, and analyzing massive data sets.
HBase is an open-source distributed NoSQL database that stores sparse data in tables consisting of billions of rows and columns. It is written in Java and modeled after Google’s big table. HBase provides support for all kinds of data and built on top of Hadoop. HBase is used when we need to search or retrieve a small amount of data from large data sets.
For example: If we are having billions of customer emails and we need to find out the customer name who has used the word replace in their emails. The request needs to be processed quickly, and for such problems, HBase was designed.
There are two main components in HBase. They are:
- HBase Master: HBase Master negotiates load balancing across the region server. It is not the actual data storage. It controls the failover, maintains, and monitors the Hadoop cluster.
- Region Server: Region Server is the worker node that handles the read, write, update, and delete requests from the clients. Region Server runs on the DataNode in HDFS.
Features of HBase:
- Scalable storage.
- It Supports fault-tolerant feature.
- Support for real-time search on sparse data.
- Support easily consistent read and writes.
8. Apache Storm
