Subject Re: Set minimum version of Hadoop 3 to JDK 8
Date Wed, 22 Apr 2015 03:38:55 GMT
A few options:

* Only change the builds for master to use jdk8
* build with both jdk7 and jdk8 by copying jobs
* build with both jdk7 and jdk8 using a jenkins matrix build

Robert, if you'd like help with any of these please send me a ping off-list.
