[jira] [Commented] (HADOOP-16219) [JDK8] Set minimum version of
Hadoop 2 to JDK 8
[ https://issues.apache.org/jira/browse/HADOOP-16219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16804254#comment-16804254 ]
Steve Loughran commented on HADOOP-16219:
-----------------------------------------
This is a more significant decision than a JIRA; needs to be discussed on the lists. Before worrying about that, let's see what happens with the builds. Closed the first PR as I managed to find the hadoop 3 -> java 8 patch and went with that one

> Key: HADOOP-16219
> URL: https://issues.apache.org/jira/browse/HADOOP-16219
> Project: Hadoop Common
> Issue Type: Improvement
> Components: build
> Affects Versions: 2.10.0
> Reporter: Steve Loughran
> Priority: Major
>
> Java 7 is long EOL; having branch-2 require it is simply making the release process a pain (we aren't building, testing, or releasing on java 7 JVMs any more, are we?).
> Staying on java 7 complicates backporting, JAR updates for CVEs (hello Guava!) &c are becoming impossible.
> Proposed: increment javac.version = 1.8
