Subject [jira] [Updated] (HADOOP-10280) Make Schedulables return a configurable identity of user or group
Date Thu, 27 Feb 2014 21:25:22 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10280?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Li updated HADOOP-10280:
------------------------------

    Description: 
In order to intelligently schedule incoming calls, we need access to members of the Call object.


We do this by defining the Schedulable interface, which has one method, getIdentity(IdentityType
idType)

The scheduler can then query a Schedulable object for its identity, depending on what idType
is. 

In this initial version, idType can be username or primary group. In future versions, it could
be jobID, request class (read or write), or some explicit QoS field.
