To access the Hue web UI, you are advised to use a browser that is compatible with the Hue WebUI, 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 Manager and Hue web UI for the first time. Otherwise, the Hue web UI cannot be accessed.
Prerequisites
When Kerberos authentication is enabled, you have been assigned the permission to access Hive by the MRS cluster administrator. For example, create a human-machine user named hueuser, add the user to user groups hive (the primary group), hadoop, and supergroup, and role System_administrator.
This user is used to log in to the Hue WebUI.
Procedure
- Log in to the service page, click the cluster name to go to the cluster details page, and choose Components.
If the Components tab is unavailable, complete IAM user synchronization first. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)
- Select Hue WebUI, click the link to log in to the Hue web UI as user hueuser.
. On the right side of
Hue WebUI provides the following functions:
- If Hive is installed in the MRS cluster, you can use Query Editors to execute query statements of Hive. Hive has been installed in the MRS cluster.
- 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
to view directories and files in HDFS.
- If Yarn is installed in the MRS cluster, you can use
to view all jobs in the MRS cluster.
- When you log in to the Hue web UI as user hueuser for the first time, you need to change the password.
- After obtaining the URL for accessing the Hue web UI, you 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 WebUI only but not on Manager, you must enter the password of the current login user when accessing Manager again.
