Wei-Chiu Chuang commented on HADOOP-12711:
------------------------------------------
I'm still working on it. The issue is there's no good equivalent of
URIUtil.encodeWithinPath(), which is used to implement
ServiceUtil.encodeQueryValue(). But I have a plan which can use URIBuilder() to
achieve the same thing, and remove ServiceUtil.encodeQueryValue() entirely. I
should be able to post a patch soon.

> This is a branch-2 only change, as ServletUtil for trunk removes the code
> that depends on commons-httpclient.
> We need to retire the use of commons-httpclient in Hadoop to address the
> security concern in CVE-2012-5783
> http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-5783.
