Fwd: [jira] [Created] (HADOOP-16219) Hadoop branch-2 to set java language version to 1.8

I've just created a patch to update branch-2 to Java 8. Not sure what's
going to break, but hopefully all problems can be done with some selective
changes. We know that Hadoop branch-2 builds and runs on Java 8, it being
the java version we are already using for our branch-2 build and test runs.

It's time to move on; maintenance is getting harder and harder, as well as
more inconvenient. And while I know of clusters being deployed, they are,
AFAIK, branch-2 on java 8 JVMs. This is just changing the language to
reflect the reality.

Before anyone asks, yes, our compatibility guidelines cover this; we had
the same issue in the java 6 -> 7 move, remember?

             Summary: Hadoop branch-2 to set java language version to 1.8
                 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


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

jvm builds, it's just the docker/jenkins stuff I'll need help on. Any
volunteers?

As Steve mentioned on the JIRA, unsupported JVM is called out as an
exception in the compatibility guidelines:

"The JVM requirements will not change across point releases within the same
minor release except if the JVM version under question becomes unsupported"
