Configure YARN with Hue

The Hue Yarn Module is enabled by default.

Enable YARN integration

Configure YARN permissions

Hue requires permission to:

Configure the permissions based on whether Ranger manages YARN authorization.

2. Grant the Hue user permission to submit applications and administer the required queue.

By default, Hue uses the default YARN queue. Ensure that the Hue user has the required permissions for at least this queue.

If Ranger isn't enabled:

1. In the Ambari UI, select the grid icon in the upper-right corner.

1. Select Yarn Queue Manager.
