Unblacklist a blacklisted tracker (at job level)?
I'm currently running a long-running job. One of our nodes was
misconfigured, however, and so got blacklisted in the job.
I've since corrected the problem, though, and restarted the tasktracker.
But how can I "un-blacklist" the tasktracker so that the job starts
using it again?
TIA,
DR

I'm once again finding myself in this same situation, but still have no
solution. I have 4 task trackers that were black-listed at the job
level. I've since fixed the issue that got them blacklisted. But the
job still isn't assigning them tasks. Is there any way to clear the
blacklist at the job level? I already tried restarting the tasktracker
on the machines, but that didn't do it.
Thanks,
DR

Thanks, but it doesn't. According to the link, restarting the task
tracker should take the node off the blacklist. That didn't happen. I
restarted the task tracker, but the node remained blacklisted for that
job. (Which is why I posted this question in the first place.)
