An error page is displayed when the Hue web UI is accessed.

Symptom

The following error information is displayed on the Hue web UI:

503 Service Unavailable
The server is temporarily unable to service your requster due to maintenance downtime or capacity problems.Please try again later.

Cause Analysis

  • The Hue configuration has expired.
  • The configuration of the Hue service needs to be modified manually in a single-master cluster.

Procedure

  1. Log in to the Master node.
  2. Run the hostname -i command to obtain the IP address of the local host.
  3. Run the following command to obtain the value of HUE_FLOAT_IP:

    grep "HUE_FLOAT_IP" ${BIGDATA_HOME}/MRS_Current/1_*/etc*/ENV_VARS, where MRS is subject to the actual file name.

  4. Check whether the local IP address is the same as the value of HUE_FLOAT_IP. If they are different, change the value of HUE_FLOAT_IP to the local IP address.
  5. Restart the Hue service.
