Allen Wittenauer updated HADOOP-14696:
--------------------------------------
Attachment: HADOOP-14696.05.patch
-05:
* A completely different implementation. This one also supports setting
per-core values for testsThreadCount. e.g., mvn -DtestsThreadCount=1.5C will
run 1 and a half tests per core.
* Also get the calculated value of testsThreadCount from within the Hadoop test
universe. (This is with an eye towards the MR tests.)
