This topic describes how to create an EMR HIVE node. EMR HIVE nodes allow you to use SQL-like statements to read data from, write data to, and manage data warehouses with a large amount of data stored in a distributed storage system. With EMR Hive nodes, you can efficiently analyze a large amount of log data.

Note The EMR module is available on the DataStudio page only after you bind an E-MapReduce computing engine to the current workspace on the Workspace Management page. For more information, see Configure a workspace.
  1. Log on to the DataWorks console. In the left-side navigation pane, click Workspaces. On the Workspaces page, find the target workspace and click Data Analytics in the Actions column.
  2. Move the pointer over the Create icon and choose EMR > EMR HIVE.

    You can also find the target workflow, right-click EMR, and choose Create > EMR HIVE.

  3. In the Create Node dialog box that appears, enter the node name, select the target folder, and click Commit.
    Note A node name can be up to 128 characters in length.
  4. On the node configuration tab, select an E-MapReduce computing engine from the Engine Instance EMR drop-down list and edit the code of the node.
  5. Configure the node properties.

    Click the Properties tab in the right-side navigation pane. On the Properties tab that appears, set the relevant parameters. For more information, see Properties.

  6. Commit the node.

    After the node properties are configured, click the Save icon in the upper-left corner. Then, commit or commit and unlock the node to the development environment.

  7. Deploy the node.

    For more information, see Deploy a node.

  8. Test the node in the production environment.
