Vinod K V commented on MAPREDUCE-890:
-------------------------------------

For some reason, Hudson's couldn't report which tests failed on its web portal, 
even though the console output is still there. I've downloaded the console 
output and saw that all the tests passed except TestTaskTrackerMemoryManager. 
And this failure is because of the same wierd java.lang.NoClassDefFoundError on 
some core classes that's been plaguing other test runs, this time on 
org.apache.hadoop.http.HttpServer$QuotingInputFilter.

I could run TestTaskTrackerMemoryManager successfully. I am going to check this 
in.

> After HADOOP-4491, the user who started mapred system is not able to run job.
