>                 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
