Enable SSL Encryption Between Hue and Hive

Hue automatically determines when SSL encryption is enabled in Hive by reading the hive-site.xml file.
Note: Starting from MEP 6.0.0, SSL encryption is enabled by default for Hive in a secured cluster. To configure SSL for Hive on a non-secure cluster, refer to Hive Encryption.
  1. The following example shows how to correctly configure the directory path where the hive-site.xml file is located in the hive_conf_dir property in [beeswax] section of the hue.ini file:
    [beeswax]
       ...
       # Hive configuration directory, where hive-site.xml is located
       hive_conf_dir=/opt/mapr/hive/hive-2.3/conf
  2. The following examples show how to enable or disable Hue verification of service certificates by configuring ssl_cacerts and ssl_validate properties in [desktop] section of the hue.ini file:
    Example for enabling certificate verification:
    [desktop]
       ...
                
      # Path to default Certificate Authority certificates. As example: /path/to/cacert.pem
      ssl_cacerts=/opt/mapr/conf/ssl_truststore.pem
                
      # Choose whether Hue should validate certificates received from the server.
      ssl_validate=true
    Example for disabling certificate verification:
    [desktop]
       ...
                
       # Path to default Certificate Authority certificates. As an example: /path/to/cacert.pem
       # ssl_cacerts=
                
       # Choose whether Hue should validate certificates received from the server.
       ssl_validate=false  
  3. After you change these properties, restart Hue to apply your changes:
    maprcli node services -name hue -action start -nodes <hostname>
