    Description

      In the context of Hadoop-On-Demand (HOD), we want to be able to aggregate metrics across the machines in the virtual cluster that corresponds to a HOD session. To enable this, we'd like to tag all the map/reduce related metrics with a session id. The session id would be a string created by HOD (it might be a Torque job id) and put into the hadoop-site.xml file for the virtual cluster.

      The default value for the session id would be the empty string, so that non-HOD usage of the metrics is not affected accept for the addition of a tag which is always the empty string.
