Subject [jira] [Created] (YARN-257) NM should gracefully handle a full local disk
Date Tue, 04 Dec 2012 17:49:58 GMT
Jason Lowe created YARN-257:
-------------------------------

             Summary: NM should gracefully handle a full local disk
                 Key: YARN-257
                 URL: https://issues.apache.org/jira/browse/YARN-257
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 0.23.5, 2.0.2-alpha
            Reporter: Jason Lowe


When a local disk becomes full, the node will fail every container launched on it because
the container is unable to localize.  It tries to create an app-specific directory for each
local and log directories.  If any of those directory creates fail (due to lack of free space)
the container fails.

It would be nice if the node could continue to launch containers using the space available
on other disks rather than failing all containers trying to launch on the node.

This is somewhat related to YARN-91 but is centered around the disk becoming full rather than
the disk failing.
