Deploying, provisioning, managing, and monitoring a Hadoop cluster requires expert scripting knowledge and usually takes a good amount of effort and time manually, but is repetitive. For performing such activities in Hadoop, we can use tools such as Ambari.
Ambari can be used by application developers and system integrators for managing most of the administration activities in a Hadoop cluster. Ambari is an open source framework in the Hadoop ecosystem, which can be used for installing, provisioning, deployment, managing, and monitoring a Hadoop cluster. Ambari's main motive is to hide the complexity of the Hadoop cluster management and to provide a very easy and intuitive web UI. One key feature of Ambari is that it provides RESTful APIs, which can be used to integrate with other external tools for better management.
