Hemanth Yamijala commented on HADOOP-3483:
------------------------------------------
Actually, the attached patch is incorrect. It will try to deallocate
(incompletely) an allocated cluster which is not still dead. There should be
additional checks. Will upload a new patch.
> [HOD] Improvements with cluster directory handling

> The following improvements are asked for from users related to cluster
> directory handling:
> - Create a new cluster directory if one does not exist.
> - If a cluster directory points to a dead cluster, currently allocate fails
> with a message asking user to deallocate it first. Instead, it should issue a
> warning, deallocate the cluster and automatically allocate a fresh one.
