Jay Finger commented on HADOOP-8110:
------------------------------------
I frequently see the same failure. I don't normally spend time in the HDFS code
so am embarrassed to say that I haven't really tried to troubleshoot this.
Assertion is same as mentioned above. Here's the test's "-output.txt" file, in
case this rings a bell for somebody:
