Hemanth Yamijala updated HADOOP-2848:
-------------------------------------
Attachment: 2848.patch
The attached file modifies the behavior of the list, info and deallocate
commands when the cluster directory is not found.
list : will list the cluster state as 'cluster state unknown' and continue to
print the cluster id and cluster directory. Previously, it used to not print
anything
info: will print that the cluster directory is invalid, and print the cluster
id, if the cluster directory was deleted.
deallocate: will print that the cluster directory is invalid, and deallocate
the cluster, based on the cluster id, if the cluster directory was deleted,
thus freeing up nodes.
The patch also adds unit tests for testing the above conditions.
> [HOD] If a cluster directory is deleted, hod -o list must show it, and
> deallocate should work.

> Currently if the cluster directory is deleted, all state about the cluster is
> lost. While this in itself is not a problem, at least recovery in the sense
> of being able to list the torque job id and deallocation to clear up the
> nodes should happen correctly.
