Doug Cutting commented on HADOOP-1473:
--------------------------------------
> Base-36 numbers are ugly and hard for users to remember and distinguish.
Longer numbers are harder to remember and distinguish. Personally, it is
easier for me to remember "jkx3y7" than "200706081453". In both cases, if I'm
scanning visually I'm likely to check only the last few digits.
> I often have people tell me look at job 75 on node1000.
That would change to "look at job 23 on node1000". Is that onerous? Even if
it were "look at job 2v" would that be a problem?

> I'll make the job ids unique across JobTracker restarts by adding the startup
> time of the JobTracker, so if the JobTracker started at 8 Jun 2007 14:50, the
> first job would be called:
> job_200706081450_00001
> the second job would be:
> job_200706081450_00002
> and so on...
