Subject [jira] [Commented] (HADOOP-12356) CPU usage statistics on Windows
Date Sun, 03 Jan 2016 04:06:39 GMT

Inigo Goiri commented on HADOOP-12356:
--------------------------------------

I don't think the failed unit test is related with the patch.

Regarding the patch itself, not sure if v8 is better than v7 as it modifies
many other methods than the initial intent. You guys call it; I don't have
a strong opinion.
