Rod Taylor commented on NUTCH-108:
----------------------------------
I have seen this as well.
When I took a look the JobTracker had knowledge of all of the events (via
localhost:7845) but did not have any trackers connected to it. The trackers on
all 5 machines had stopped running. After restarting the trackers the system
continued from where it left off.
Snipped from one tracker log. All tracker logs looked similar.
