------------------------------------------

Aleksey,

I tried it again in a clean checkout. The first time I ran the tests they 
passed, but then when I ran them again one failed:

testDeleteFileInfo(org.apache.hadoop.mapreduce.v2.hs.TestJobHistoryParsing)

I am using java7 too so order of tests within there might be an issue.

Note that I can run it by hand a bunch of times with mvn test 
-Dtest=TestJobHistoryParsing and it intermittently fails
