Josh Wills updated CRUNCH-355:
------------------------------
Attachment: CRUNCH-355.patch
Wrote a patch for this that keeps the jobID the same, but adds a sequence
number so that the (n/m) counts are correct based on the order that the jobs
are kicked off in at runtime.
> Rename jobs to show how many stages have done before job submission

> The naming mechanism introduced in CRUNCH-262 has a flaw. It adds (m/n) to
> the end of job name, where m is the current stage number at planning time and
> n is the total number of stages.
> Suppose in the following case, where A takes a long time to run, when B is
> submitted, C and D have completed. As there are 3 jobs done, we should expect
> B to be (4/5) rather than (2/5) or (3/5).
> {code}
> A C
> | |
> B D
> \ /
> E
> {/code}
> In planning time, we don't have a clue which stage will complete earlier. So
> I think it better to assign it at runtime.
> One problem here is that the user may access to Job instance before it
> submits. So he may observe a sudden change of job name.
