Subject Re: Looking to a Hadoop 3 release
Date Tue, 10 Mar 2015 02:23:14 GMT
Avoiding the use of JDK8 language features (and, presumably, APIs)
means you've abandoned #1, i.e., you haven't (really) bumped the JDK
source version to JDK8.

Also, note that releasing from trunk is a way of achieving #3, it's
not a way of abandoning it.
