• Adding option to build NNA with HDFS 2.10.0
• Fix problem with dependency on commons-io
• Add eclipse plugin

Guess need to update supported versions in the doc.

Hey Konstantin. Sorry it has been a while. Can you please re-base to the latest commit on master branch and push to your PR branch again? It turns out Travis CI (in the way I was using it) is deprecated now and so no CI was happening for NNA.

I have merged in the commons-io fix as that was affecting the entire build, so your new PR should be simpler.

Again, sorry, but at least next PR push will have CI for build.

One more thing will need to be updated, should be done here as part of this issue:

• Build matrix environment variable for 2.10 : https://github.com/paypal/NNAnalytics/blob/master/.github/workflows/gradle.yml

[shvachko]

Rebased the patch. Updated gradle.yml
