Subject [jira] [Updated] (YARN-291) Dynamic resource configuration
Date Thu, 13 Jun 2013 09:59:25 GMT

     [ https://issues.apache.org/jira/browse/YARN-291?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Junping Du updated YARN-291:
----------------------------

    Description: The current Hadoop YARN resource management logic assumes per node resource
is static during the lifetime of the NM process. Allowing run-time configuration on per node
resource will give us finer granularity of resource elasticity. This allows Hadoop workloads
to coexist with other workloads on the same hardware efficiently, whether or not the environment
is virtualized. More background and design details can be found in attached proposal.  (was:
