Subject [jira] [Commented] (MESOS-397) Framework should be notified of executor directory deletion
Date Thu, 14 Mar 2013 19:58:13 GMT


Benjamin Mahler commented on MESOS-397:

One problem is that the slave has the concept of executor "runs". That is, different runs
of an executor with a fixed id. This can happen when the executor completes, fails, etc.,
and the framework continues to use the executor id on that slave.

What would the framework be notified of? When a run directory is deleted? When the uppermost
executor directory is deleted?

If we coarsened the gc granularity and only deleted top level executor directories, then the
directory could still be recreated afterwards when the framework uses that executor id again
to launch a task.

> The framework currently receives no signal regarding the deletion of executor work directories,
which suggests that _something_ else is watching them.  To close the loop, the slave should
notify the framework when directories are deleted.
