Data is quite crucial in today’s world, and with a growing amount of data, it is quite tough to manage it all. A large amount of data is termed as Big Data. Big Data includes all the unstructured and structured data, which needs to be processed and stored. Hadoop is an open-source distributed processing framework, which is the key to step into the Big Data ecosystem, thus has a good scope in the future.
With Hadoop, one can efficiently perform advanced analytics, which does include predictive analytics, data mining, and machine learning applications. Every framework needs a couple of tools to work correctly, and today we are here with some of the hadoop tools, which can make your journey to Big Data quite easy.
Top 10 Hadoop Tools You Should Master
Hadoop Distributed File System, which is commonly known as HDFS is designed to store a large amount of data, hence is quite a lot more efficient than the NTFS (New Type File System) and FAT32 File System, which are used in Windows PCs. HDFS is used to carter large chunks of data quickly to applications. Yahoo has been using Hadoop Distributed File System to manage over 40 petabytes of data.
Apache, which is commonly known for hosting servers, have got their solution for Hadoop’s database as Apache HIVE data warehouse software. This makes it easy for us to query and manage large datasets. With HIVE, all the unstructured data are projected with a structure, and later, we can query the data with SQL like language known as HiveQL.
HIVE provides different storage types such as plain text, RCFile, Hbase, ORC, etc. HIVE also comes with built-in functions for the users, which can be used to manipulate dates, strings, numbers, and several other types of data mining functions.

Structured Query Languages have been in use since a long time, now as the data is mostly unstructured, we require a Query Language which doesn’t have any structure. This is solved mainly through NoSQL.
Here we have primarily key pair values with secondary indexes. NoSQL can easily be integrated with Oracle Database, Oracle Wallet, and Hadoop. This makes NoSQL one of the widely supported Unstructured Query Language.
Apache has also developed its library of different machine learning algorithms which is known as Mahout. Mahout is implemented on top of Apache Hadoop and uses the MapReduce paradigm of BigData. As we all know about the Machines learning different things daily by generating data based on the inputs of a different user, this is known as Machine learning and is one of the critical components of Artificial Intelligence.
Machine Learning is often used to improve the performance of any particular system, and this majorly works on the outcome of the previous run of the machine.

With this tool, we can quickly get representations of complex data structures that are generated by Hadoop’s MapReduce algorithm. Avro Data tool can easily take both input and output from a MapReduce Job, where it can also format the same in a much easier way. With Avro, we can have real-time indexing, with easily understandable XML Configurations for the tool.
6) GIS tools
Geographic information is one of the most extensive sets of information available over the world. This includes all the states, cafes, restaurants, and other news around the world, and this needs to be precise. Hadoop is used with GIS tools, which are a Java-based tool available for understanding Geographic Information.
With the help of this tool, we can handle Geographic Coordinates in place of strings, which can help us to minimize the lines of code. With GIS, we can integrate maps in reports and publish them as online map applications.
LOGs are generated whenever there is any request, response, or any type of activity in the database. Logs help to debug the program and see where things are going wrong. While working with large sets of data, even the Logs are generated in bulk. And when we need to move this massive amount of log data, Flume comes into play. Flume uses a simple, extensible data model, which will help you to apply online analytic applications with the most ease.

All the cloud platforms work on Large data sets, which might make them slow in the traditional way. Hence most of the cloud platforms are migrating to Hadoop, and Clouds will help you with the same.
With this tool, they can use a temporary machine that will help to calculate big data sets and then store the results and free up the temporary machine, which was used to get the results. All these things are set up and scheduled by the cloud/ Due to this, the normal working of the servers is not affected at all.
Coming to hadoop analytics tools, Spark tops the list. Spark is a framework available for Big Data analytics from Apache. This one is an open-source data analytics cluster computing framework that was initially developed by AMPLab at UC Berkeley. Later Apache bought the same from AMPLab.
Spark works on the Hadoop Distributed File System, which is one of the standard file systems to work with BigData. Spark promises to perform 100 times better than the MapReduce algorithm for Hadoop over a specific type of application.
Spark loads all the data into clusters of memory, which will allow the program to query it repeatedly, making it the best framework available for AI and Machine Learning.

Hadoop MapReduce is a framework that makes it quite easy for the developer to write an application that will process multi-terabyte datasets in parallel. These datasets can be calculated over large clusters. MapReduce framework consists of a JobTracker and TaskTracker; there is a single JobTracker which tracks all the jobs, while there is a TaskTracker for every cluster-node. Master i.e., JobTracker, schedules the job, while TaskTracker, which is a slave, monitors them and reschedule them if they failed.
Bonus: 11) Impala
Cloudera is another company that works on developing tools for development needs. Impala is software from Cloudera, which is leading software for Massively Parallel Processing of SQL Query Engine, which runs natively on Apache Hadoop. Apache licenses impala, and this makes it quite easy to directly query data stored in HDFS (Hadoop Distributed File System) and Apache HBase.
The Scalable parallel database technology used with the Power of Hadoop enables the user to Query data easily without any issue. This particular framework is used by MapReduce, Apache Hive, Apache Pig, and other components of Hadoop stack.
These are some of the best in hadoop tools list available by different providers to work on Hadoop. Although all the tools are not necessarily used on a single application of Hadoop, they can easily make the solutions of Hadoop easy and quite smooth for the developer to have a track on the growth.
