template: 'Hadoop by HTTP'
name: 'Hadoop by HTTP'
description: |
The template gets the Hadoop metrics from cluster's hosts (ResourceManager, NodeManagers, NameNode, DataNodes) by HTTP agent. You should define the IP address (or FQDN) and Web-UI port for the ResourceManager in {$HADOOP.RESOURCEMANAGER.HOST} and {$HADOOP.RESOURCEMANAGER.PORT} macros and for the NameNode in {$HADOOP.NAMENODE.HOST} and {$HADOOP.NAMENODE.PORT} macros respectively. Macros can be set in the template or overridden at the host level.
You can discuss this template or leave feedback on our forum https://www.zabbix.com/forum/zabbix-suggestions-and-feedback/413459-discussion-thread-for-official-zabbix-template-hadoop
