Hi guys: I'm getting an odd error involving a file called toBeDeleted.
I've never seen this - somehow its blocking my task trackers from starting.
2013-03-06 16:19:24,657 ERROR org.apache.hadoop.mapred.TaskTracker: Can not
start task tracker because java.lang.RuntimeException: Cannot find root
interesting: The solution was simply to delete the toBeDeleted directory
manually:
rm -rf /usr/lib/hadoop/mapred/toBeDeleted/
I guess maybe somehow I changed the privileges of the
/usr/lib/hadoop/mapred directory so that it was unreadable or something.
Nevertheless, it was a cryptic error
