Subject Re: [DISCUSS] Set minimum version of Hadoop 3 to JDK8 (HADOOP-11858)
Date Tue, 17 May 2016 03:02:18 GMT
	OK, it looks like if someone commits HADOOP-13161, then trunk only uses JDK8 and branch-2
will use JDK7 and JDK8 during precommit with no changes required to Apache Yetus. :D

 (This effectively means that *ALL* JDK7 testing will *ONLY* be happening in the regularly
scheduled builds)
