[sahara-image-elements] Make jdk source configurable and migrate to OpenJDK

[Matthew Farrellee]

Instead of always using a pre-downloaded oracle java tarball, or downloading one as part of image customization, it should be possible to just package-install java and thus use the distribution's Java.

[Sergey Lukjanov (slukjanov)]

Are there official packages of Oracle Java in both Ubuntu and Fedora?

[Matthew Farrellee (mattf)]

Fedora only provides OpenJDK. It should be the choice of the image builder what Java they want to use.

It's entirely reasonable that "supported" images may have specific versions of Java from specific vendors installed.

I'm only proposing there be choice in how the Java elements work.

Does Hadoop work on top of OpenJDK?

[Matthew Farrellee (mattf)]

That's quite a question. I can say that we have yet to run into issues that are unique to OpenJDK.
