Accessing the Hue Web UI

Updated at: Apr 28, 2020 GMT+08:00


After Hue is installed for an MRS cluster, users can use Hadoop and Hive on the Hue web UI.

This section describes how to open the Hue web UI on the MRS cluster.

  • To access the Hue web UI, you are advised to use a browser that is compatible with the Hue web UI, for example, Google Chrome 50. The Internet Explorer may be incompatible with the Hue web UI.

Impact on the System

Site trust must be added to the browser when you access MRS Manager and Hue web UI for the first time. Otherwise, the Hue web UI cannot be accessed.


When Kerberos authentication is enabled, the MRS cluster administrator has assigned the permission for using Hive to the user. For details, see Creating a User. For example, create a human-machine user hueuser and add it to the hive and the System_administrator role.


  1. On the MRS cluster details page, click Components.

    • If the Components tab is not displayed on the cluster details page, complete IAM user synchronization first. (On the Dashboard tab page of the cluster details page, click on the right side of IAM User Sync to synchronize IAM users.)
    • For MRS 1.8.10 or earlier, log in to MRS Manager. For details, see Accessing MRS Manager. Then, choose Services.

  2. Choose Hue. In Hue Web UI of Hue Summary, click Hue (Active). The Hue web UI is opened.

    The Hue web UI provides the following functions:

    • If Hive is installed in the MRS cluster, you can use Query Editors to execute query statements of Hive.
    • If Hive is installed in the MRS cluster, you can use Data Browsers to manage Hive tables.
    • If HDFS is installed in the MRS cluster, you can use File Browser to view directories and files in HDFS.
    • If Yarn is installed in the MRS cluster, you can use Job Browser to view all jobs in the MRS cluster.
    • After obtaining the URL for accessing the Hue web UI, the user can give the URL to other users who cannot access MRS Manager for accessing the Hue web UI.
    • If you perform operations on the Hue web UI only but not on MRS Manager, you must enter the password of the current login user when accessing MRS Manager again.
