Distributed storage and distributed processing of large data sets have always been a challenge for IT admins. This increasing need to store and process large data sets efficiently led to the development of the Hadoop framework. With its massive storage capacity and enormous processing power, Hadoop allows users to manage ever increasing data sets and perform tasks easily. However, it is important to ensure the smooth functioning of the Hadoop framework. With Applications Manager, it's easy to get operational insight about your Hadoop environment, connect to Hadoop clusters via REST API or JMX, maintain optimal health of distributed Hadoop clusters, and ensure that your clusters are available and processing tasks quickly and accurately.
