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

    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.)
