Hemanth Yamijala updated HADOOP-2848:
-------------------------------------
Attachment: 2848.1.patch
Vinod, thanks for the review.
The attached patch fixes the problems identified in the review. In the process,
I modified the error codes and messages for some of the operations so that they
are now consistent.
The behavior of the list, info and deallocate commands for a directory that was
previously allocated, but was subsequently deleted, or recreated would be the
same in that we would identify that this was a previously allocated directory
and give out a message accordingly.
The allocate command will now fail if the cluster directory was found to be
allocated (or recreated)
If an invalid directory is given to info or deallocate, it would just print a
message saying the directory is invalid and fail.
> [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.
