Sanjay Radia commented on HADOOP-7015:
--------------------------------------

We don't have good MT tests  for our file systems and they are not easy to write. 
However, the loadGenerator (an MT filesystem load generator) is a good MT tests for the basic file system operations;  I discovered this bug when running it and it now passes with my patch. I think we should incorporate the loadGenerator as part of our commit tests (since it runs for a while); I was planning to file a jira to do that. 
Would incorporating the loadGenerator as part of our commit tests be good enough?
(Will fix the Arrays#copyOf ....).
