Subject Re: [DISCUSS] Set minimum version of Hadoop 3 to JDK8 (HADOOP-11858)
Date Tue, 17 May 2016 13:52:47 GMT

Thanks to Karthik’s +1, HADOOP-13161 was committed last night and appears to be working.

	I’ve got almost the entire list of stuff finished.  I’m now going to go through the java8
jobs and actually sync them up, since they all do slightly different things. :/

will use JDK7 and JDK8 during precommit with no changes required to Apache Yetus. :D
