Hue and High Availability

If your cluster has HDFS high availability enabled, you must configure the Hue HDFS Web Interface Role property to use HttpFS. See Configuring Hue to Work with HDFS HA Using Cloudera Manager for detailed instructions.

To configure the Hue service itself for high availability, see Hue High Availability.
