Allen Wittenauer created HADOOP-14670:
-----------------------------------------
Summary: Increase minimum cmake version for all platforms
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
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. Plus:
* 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.
