Exp:

Gateway or gateway node or edge node

• This is a type of role that provides access to a client for a specific service from cluster services.
• Hive, HDFS, Kafka, MapReduce, Solr and Spark each have gateway roles to provide access for their clients to their respective services.
• Names: It is not mandatory that Gateway Role would have gateway name in their names and also, they may not be exclusively for client access.
• Example: Hue Kerberos Ticket Renewer is a gateway role that proxies tickets from Kerberos.
• The node supporting one or more gateway roles is sometimes referred to as the gateway node or edge node, with the notion of “edge” common in network or cloud environments.
• In terms of the Cloudera cluster, the gateway nodes in the cluster receive the appropriate client configuration files when Deploy Client Configuration is selected from the Actions menu in Cloudera Manager Admin Console.
