> Consider a scenario where hod runs allocate successfully, but isn't able to save teh allocated information to the clusters.state file. In such a case, it gets an error and exits. But the cluster remains allocated, and unfortunately the user cannot deallocate the cluster now unless he knows the cluster directory.
> It is better if HOD can deallocate the cluster in such an error condition.
