          Article Summary

          Available in VPC

          Once you create a Data Forest app, quick links will be provided for every app. This guide explains types of quick links and how to access them.

          1. AppMaster UI

          Apps run in YARN application formats, so all apps have a quick link to AppMaster. Clicking on the AppMaster link brings up the "AppMaster" page. Enter your Data Forest account and password to log in.

          Once you logged in to AppMaster, you can see all the apps owned by the user account.
          df-vpcvm_quicklink02_vpc.

          Cluster

          ItemsDescription
          AboutCluster and RM information
          NodesNode information
          Node LabelsCluster's node label information
          ApplicationsThe apps can be viewed by status (app status: NEW, NEW_SAVING, SUBMITTED, ACCEPTED, RUNNING, FINISHED, FAILED, KILLED)
          SchedulerApplication queue's details

          Tools

          ItemsDescription
          ConfigurationCluster settings information
          Local logsView each container's log. Only accounts with the admin permission can access
          Server stacksStack information
          Server metricsCluster's entire metric
          Note

          The local log page is only accessible from an account with the admin permission. Regular users can't access it. If they try to access the menu, the HTTP 403 error will appear.

          2. Web Shell UI

          It is a web shell where you can directly access the YARN container. Enter your Data Forest account and password to log in. Users can't be changed in a web shell.

          3. Supervisor UI

          The supervisor monitors whether ES processes running in different containers are live, and manages them. You can restart or stop an ES process, or view its logs. A supervisor UI exists for each node role.

          • supervisor-es-ingest-0: it manages ingest node processes.
          • supervisor-es-coord-0: it manages coordinating node processes.
          • supervisor-es-data-0: it manages data node processes.
          • supervisor-es-master-0: it manages master node processes.

          Log in by entering the Data Forest account and password to see the screen as below.
          df-appquicklink_04_vpc_ko

          4. HTTP REST API address

          Apps such as Elasticsearch and Spark History Server provide REST APIs. Use the HTTP REST API address for the configuration required for integration.

          5. JDBC connection string

          The JDBC connection string provided by the Apache Hive app is a connection string used when connecting with JDBC from Beeline, Apache Zeppelin, Apache Hue, or a user-defined program.

          Set quick links access

          To access the quick links of the app created in Data Forest, create a notebook first. After completing the notebook creation, you can connect to the notebook server through SSH tunneling and then access Data Forest quick links.
          df-vpcvm_06_vpc

          1. Create notebook
