Subject [jira] [Created] (YARN-3531) Make "good" local directories available to ContainerExecutors at initialization time
Date Wed, 22 Apr 2015 18:48:59 GMT
Sidharta Seethana created YARN-3531:
---------------------------------------

             Summary: Make "good" local directories available to ContainerExecutors at initialization
time
                 Key: YARN-3531
                 URL: https://issues.apache.org/jira/browse/YARN-3531
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Sidharta Seethana


Currently, in the NodeManager's serviceInit() function, the configured executor is initialized
before the node health checker/directory handler service are initialized. There are use cases
where executor initialization requires access to 'good' local directories ( e.g for creation
of temporary files , see YARN-3366 ).  We need to figure out a way to make this possible.
