Just in case anyone else has a similar problem, I happened across this command 
just before I was about to kill my job:

hadoop job [-fail-task <task-id>]

I was able to fail the offending task (specifying the task attempt ID, of 
course - see https://issues.apache.org/jira/browse/MAPREDUCE-985), a new 
attempt was immediately launched, and the job completed successfully. Hooray!

FYI,

- Chris
