    [ https://issues.apache.org/jira/browse/HADOOP-14670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16168559#comment-16168559

Wangda Tan commented on HADOOP-14670:

Thanks comments [~aw]/[~chris.douglas], I will investigate on my local build environment to
see what's the best option. Downgrading priority to major.

>                 Key: HADOOP-14670
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14670
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: build
>    Affects Versions: 3.0.0-beta1
>            Reporter: Allen Wittenauer
>            Assignee: Allen Wittenauer
>            Priority: Blocker
>             Fix For: 3.0.0-beta1
>         Attachments: HADOOP-14670.00.patch, HADOOP-14670.01.patch, HADOOP-14670.02.patch,
> cmake 2.6 is old at this point and I'd be greatly surprised if anyone is actually using
it or testing against it.  It's probably time to upgrade to something approaching modern.
> * Mac OS X already requires 3.0
> * If HADOOP-14667 gets committed, Windows bumps to 3.1
> * There is special handling in at least one CMakeLists.txt for versions less than 3.1
> Given the last two points, I'd propose making the minimum 3.1, if not something higher
due to  compiler support for newer compilers across all platforms.
