Setting up Hadoop Service URLs
To configure access to an internal Hadoop service through the Knox Gateway:
Edit
$gateway/conf/topologies$cluster-name.xml
to add an entry similar to the following, for each Hadoop service:<topology> <gateway> ... </gateway> <service> <role> $service_name </role> <url> $schema://$hostname:$port</url> </service> </topology>
where:
$service_name
is either WEBHDFS, WEBHCAT, WEBHBASE, OOZIE, HIVE, NAMENODE, AMBARI, AMBARIUI, RANGER. AMBARIUI, or JOBTRACKER.<url>
is the complete internal cluster URL required to access the service, including:$schema
-- the service protocol$hostname
-- the resolvable internal host name$port
-- the service listening port
Save the file.
The gateway creates a new WAR file with modified timestamp in
$gateway/data/deployments
.Note It is not necessary to restart the Knox server after making changes to the topology/Hadoop Cluster services.
