--------------------------------

             Summary: Old slave directories should not be garbage collected 
based on file modification time
                 Key: MESOS-419
                 URL: https://issues.apache.org/jira/browse/MESOS-419
             Project: Mesos
          Issue Type: Sub-task
            Reporter: Vinod Kone
            Assignee: Vinod Kone


Since running executors, do not change the modification time of the slave work 
directory, it would be bad to schedule old slave directories for deletion based 
on their mod time. Instead, these work directories should be scheduled for gc 
based on the 'gc_delay' flag.

At Twitter, this manifested as task directories getting immediately gc'ed when 
long running slaves were rolled for an upgrade.
