Setting Up a Hostmap Provider
Add the hostmap
provider to the
cluster topology descriptor and a parameter for each DataNode in the cluster, as follows:
Open the cluster topology descriptor file,
$cluster-name.xml
, in a text editor.Add the Hostmap provider to
topology/gateway
using the following format:<provider> <role>hostmap</role> <name>static</name> <enabled>true</enabled> <param> <name>$external-name</name> <value>$internal-dn-host</value> </param> </provider>
where:
$cluster-name.xml
is the name of the topology descriptor file, located in $gateway /conf/topologies.$external-name
is the value that the gateway uses to replace $internal_host host names in responses.$internal-dn-host
is a comma-separated list of host names that the gateway will replace when rewriting responses.
To the
hostmap
provider, add aparam
for each additional DataNode in your cluster:<param> <name>
$external-name2</name> <value>
$internal-dn2-host</value> </param>
Save the file.
Saving the results automatically deploys the topology with the change. The result is the creation of a new WAR file with modified timestamp in $gateway/data/deployments.
