Puppet Class: hadoop::historyserver::service

Defined in:
manifests/historyserver/service.pp

Overview

Class hadoop::historyserver::service

Namenode should be launched first if it is colocated with historyserver (just cosmetics, some initial exceptions in logs) (tested on hadoop 2.4.1).

It works OK automatically when using from parent hadoop::service class.
