Hadoop ecosystem contains several components like MapReduce, Hive, HBase, Zookeeper, Apache Pig, etc. These components can serve a broad spectrum of applications. Map-Reduce can be used to perform aggregation and summarization on Big Data. Hive may be a data warehouse project on the highest HDFS. Hive provides data query and analysis with SQL like interface. HBase is a NoSQL database. It provides real-time read-write to large datasets. It is natively integrated with Hadoop. The pig may be a high-level scripting language used with Hadoop. It describes the data analysis problem as data flows. One can do all the info manipulation in it with Pig. Zookeeper is an open-source server that coordinates between various distributed processes. Distributed applications use zookeeper to store and convey updates to big configuration information.

6. Research Tool

Hadoop has come about as a powerful research tool. It allows an organization to find answers to their business questions. Hadoop helps them in research and development work. Companies use it to perform the analysis. They use this analysis to develop a rapport with the customer.

Applying Big Data techniques enhance operational effectiveness and efficiencies of generating great revenue in business. It brings a better understanding of the business value and develops business growth. Communication and distribution of information between different companies are feasible via big data analytics and IT techniques. The organizations can collect data from their customers to grow their business.

7. Ease of Use

Hadoop has been written in Java, which has the biggest developer community. Therefore, it is easy to adapt by programmers. You can have the pliability of programming in other languages too like C, C++, Python, Perl, Ruby, etc. If you’re conversant in SQL, it’s easy to use HIVE. If you’re comfortable with scripting then PIG is for you. 

Hadoop framework handles all the multiprocessing of the data at the back-end. We need not worry about the complexities of distributed processing while coding. We just need to write the driver program, mapper, and reducer function. Hadoop framework takes care of how the info gets stored and processed during a distributed manner. With the initiation of Spark in Hadoop, ecosystem coding has become even easier. In MapReduce, we need to write thousands of lines of code. But in Spark, it has come down to only a few lines of code to achieve the same functionality.
