Disable an Application in the Hue Interface (optional)

About this task

If you want to disable an application (such as Impala), follow these steps:

Procedure

  1. In the [desktop] section of the hue.ini file, uncomment the # app_blacklist= statement and insert the name of the app you want to disable (impala in this example).
    NOTE
    Do not remove search from the app_blacklist. The Hue UI will not work if the search application is enabled. 
    # Comma-separated list of apps not to load at server startup.
# Note that rdbms is the name used for dbquery.
app_blacklist=spark,zookeeper,search,impala,sqoop,rdbms
    NOTE
    After removing an application from app_blacklist, you must update the Hue internal database to create the tables required for the application that was enabled:
    sudo /opt/mapr/server/configure.sh -R
  2. Once all changes are made, restart Hue so the changes will take effect.
    NOTE
    You can re-enable a blacklisted application at any time, and then restart Hue. 
    maprcli node services -name hue -action restart -nodes <ip_address>
