[jira] [Created] (MESOS-2825) Run heavy disk IO operations at low IO priority

Ian Downes created MESOS-2825:
---------------------------------

             Summary: Run heavy disk IO operations at low IO priority
                 Key: MESOS-2825
                 URL: https://issues.apache.org/jira/browse/MESOS-2825
             Project: Mesos
          Issue Type: Improvement
          Components: isolation
    Affects Versions: 0.23.0
            Reporter: Ian Downes
            Priority: Minor


Slave IO operations on large images can be disruptive to tasks, e.g., decompressing, decrypting, hashing, and extracting. Provide option to run such operations at a lower IO priority, i.e., at "idle" or by explicitly setting the "best effort" priority to less than the tasks', e.g., 0 as the lowest best effort priority. All of the existing operations in the Appc provisioner are run as Subprocesses.
