Used to monitor Metric-related configuration attributes Used to monitor whether a port on the machine is available NameNode UI, ResourceManage UI, HBase Master UI.Quick links (direct component native management interface).There is a Service Action button in the upper right corner, including operations such as service start, stop, and delete.
In the Service list on the left, the middle part is the Component information of the Service, that is, which modules and the number of the Service has.Key operation and maintenance indicators (metrics)-metrics means "metrics, indicators".For example, HBase relies on HDFS and Zookeeper, Ambari will start HDFS and Zookeeper first, and then start HBase. According to the dependencies of the Service, each Service is started in a certain order. The super administrator of the cluster has supreme rights and can operate any component. On the basis of Service Administrator, operations on hosts and components are added, such as adding, deleting, etc. On the basis of Service Operator, operations such as configuring service, moving NameNode, and enabling HA are added Able to operate the service life cycle, such as start, stop, and also perform some operations such as Rebalance DataNode and YARN refresh View cluster and service information, such as configuration, service status, and health status. Role-based user management, roles are divided into: Component Level Action (module level operation).Host Level Action (machine level operation).It has basic functions such as installation, management, operation and maintenance of Hadoop components, and provides Web UI for visual cluster management, which simplifies the difficulty of installation and use of the big data platform. Welcome to visit my blog Introduction to AmbariĪmbari is Hortonworks' open source Hadoop platform management software. During the process of using it, I compiled a part of the function list and shared it here. Recently, I was doing research on the visual deployment of Hadoop clusters, and I found Ambari this interesting thing.
