Functions of Hadoop:
Hadoop was developed in the year 2008 by Yahoo as open-source software. It is the software ecosystem where it is easy to store and process huge amounts of data. The fault tolerance is the very good function in this software where if any node goes down, then it automatically redirects the request to the other node. Distributed computing stores multiple data in all the sheets automatically. Students who are interested in data analysis and data warehousing can join the Hadoop Training Chennai to be placed in their dream Job. Any type of data and any size of data were stored in this software. Structured data, unstructured data, and small size data, big size data all are stored in the Hadoop software. There are two types of node in Hadoop such as name node and data node. Name node manages the data node. Name node records all the Metadata, location of the files, the size of the files, permissions, hierarchy etc. all these details are maintained. The map reduces functions perform functions like filtering, grouping and sorting. It does two functions such as mapping and reducing. Those who already have experience in the database can explore more things by joining in Hadoop Training in Chennai.
Map reduce is suitable for simple information and it is not suitable for iterative and interactive analytic task. Hadoop is not suitable for the small data as it is designed for the big data. The processing speed is slow in Hadoop map to reduce whereas it is 100 times faster in Hadoop spark. The challenges faced byHadoopmap reduce has been overthrown in Hadoop spark. Hadoop-spark is designed with in-memory which processes only the parts of the data, not the full data. Apache spark emphasizes on the velocity of data with takes less processing time. Apache Flink is used for batch processing application which processes the row after row in real time.
