TEZ-4287: Upgrade FindBugs to SpotBugs

[belugabehr]

[belugabehr]

How do we update the build system to call out to this new spot bugs?

[abstractdog]

I think the error is because currently, we don't use a Jenkinsfile in the repo, but tez-multibranch job (link) has the --findbugs-strict-precheck flag, which is not handled then(once we'll have Jenkinsfile we can handle this in it). I believe I can remove that temporarily in the jenkins job configuration while having this tested, is it the proper way to do @jteagles ?

UPDATE: I commented out, could you retry @belugabehr ?

[jteagles]

There is a Jenkins file in progress as a PR submission that I haven't had time to verify. If anyone has time to try this out, it may help with better integration with Yetus. https://github.com/aw-was-here/tez/commit/bead3a21e68ecf4a75d64d8c08b9f8fa0f98cf51

@jteagles : I was already looking at that patch, looks good, I'm about to adopt it piece-by-piece

[abstractdog]

@belugabehr, please rebase this PR as TEZ-4290 is merged, you might have minimal conflicts with that in Dockerfile
