HDFS, YARN, and other services are listed on the Clusters and Services tab of the cluster management page. You can view the running statuses of these services.
A service's running status is only showed for clusters that are in the Idle or Running status. Services that are not checked when creating a cluster, such as Storm, are not listed.
Click a service to view the corresponding tabs, including Status, Component Topology, Configuration, and Configuration Change History. The status can either be Normal or Error. If the status of a service on a node is Error, you can use the master node to log on to the node and check the service process.
