Stefan Will commented on HADOOP-5430:
-------------------------------------

My jobtracker log is peppered with messages like these:

2009-03-06 10:21:18,628 INFO org.apache.hadoop.mapred.JobTracker: Serious problem.  While
updating status, cannot find taskid attempt_200903032230_011
0_r_000013_3

> My cluster is currently idle, but it shows the following statistics on the jobtracker
status page:
> Maps	Reduces	Total Submissions	Nodes	Map Task Capacity	Reduce Task Capacity	Avg. Tasks/Node
> -86	4	118	26	130	78	8.00
> I would expect the Maps and Reduces columns to both be 0.
