> At very busy times - we get a wave of job client failures all at the same time. the failures come when the job is about to complete. when we look at the job history files - the jobs are actually complete. Here's the stack:
> 08/09/27 02:18:00 INFO mapred.JobClient: map 100% reduce 98%
> 08/09/27 02:18:41 INFO mapred.JobClient: map 100% reduce 99%
> java.lang.NullPointerException
