Subject [jira] Updated: (PIG-1323) Communicate whether the call to LoadFunc.setLocation is being made in hadoop's front end or backend
Date Mon, 12 Apr 2010 22:24:48 GMT

     [ https://issues.apache.org/jira/browse/PIG-1323?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pradeep Kamath updated PIG-1323:
--------------------------------

        Status: Resolved  (was: Patch Available)
    Resolution: Invalid

There is already a hadoop property "mapred.task.id" which is set to the map/reduce task id
in the backend and is not set in the front end which can be used to figure this out. Hence
it is best not to introduce new properties in the configuration for this purpose.

> Loaders which interact with external systems like a metadata server may need to know
if the LoadFunc.setLocation call happens from the frontend (on the client machine) or in the
backend (on each map task). The Configuration in the Job argument to setLocation() can contain
this information.
