I'd like us to use Hadoop 2.7.2 owing to the Hadoop release notes stating Hadoop 2.7.0 is not ready for production use

https://hadoop.apache.org/docs/r2.7.0/ states

"Apache Hadoop 2.7.0 is a minor release in the 2.x.y release line, building upon the previous stable release 2.6.0.
This release is not yet ready for production use. Production users should use 2.7.1 release and beyond."

Hadoop 2.7.1 release notes:
"Apache Hadoop 2.7.1 is a minor release in the 2.x.y release line, building upon the previous release 2.7.0. This is the next stable release after Apache Hadoop 2.6.x."

And then Hadoop 2.7.2 release notes:
"Apache Hadoop 2.7.2 is a minor release in the 2.x.y release line, building upon the previous stable release 2.7.1."

I've tested this is OK with Intel hardware and IBM Java 8 so let's test it with OpenJDK, ideally this will be pushed to branch-2.0 and master.

That's probably fine. I suppose we should do this for all of the 2.x Hadoop branches?

[a-roberts]

Good point, I see the latest Hadoop 2.6 version is 2.6.4 (mentions fixing critical bugs) and for 2.5 it's 2.5.2 (same story), so ideally we'd ensure each "best for profile" version gets used.

Should I submit the version changes with this pull request so instead it's a "Update Hadoop versions" change?

Does your build farm exercise all Hadoop permutations (so we can test the best available 2.3.x, 2.4.x, 2.5.x, 2.6.x, 2.7.x)?

[a-roberts]

Best versions for Hadoop profiles since 2.3 are as follows

2.7: 2.7.2
2.6: 2.6.4
2.5: 2.5.2 (although there's no 2.5 profile)
2.4: 2.4.1 (users immediately encouraged to move up for a security fix)
2.3: 2.3.0 (as is)

You'll have to run ./dev/test-dependencies.sh --replace-manifest to update the expected dependencies. And we can see if somehow a transitive dependency changed.

[a-roberts]

Done, didn't giff automatically so git diffed myself and see plenty of differences (as you'd expect Hadoop transitive dependencies should be, say, 2.4.1 not 2.4.0 now, 2.7.2 not 2.7.0, etc).

Where do we update the expected values? Grepping for "hadoop-annotations" for example only shows dev/deps/spark-deps_jar name_.

Looking in the script I see pr-deps is created based on the Hadoop profiles, so perhaps we need to add the explicit Hadoop version when we define the Hadoop profiles...

Sample output for 2.7:

-hadoop-annotations-2.7.0.jar
-hadoop-auth-2.7.0.jar
-hadoop-client-2.7.0.jar
-hadoop-common-2.7.0.jar

-hadoop-mapreduce-client-app-2.7.0.jar
-hadoop-mapreduce-client-common-2.7.0.jar

If you run that script it will update the deps/* files for you automatically. Just push the results so we can review them here.

LGTM
