I looked at the tar generated. I think that hadoop dependencies can be cleaned up. We should have only the client-api and client-runtime in that folder since they are supposed to have all the classes that the hadoop client needs. |

Hadoop 2 often causes red security scans on Druid distribution because of the dependencies it brings. We want to move away from Hadoop 2 and provide Hadoop 3 distribution available. Switch druid to building with Hadoop 3 by default. Druid will still be compatible with Hadoop 2 and users can build hadoop-2 compatible distribution using hadoop2 profile. (cherry picked from commit 774073b)

Description:
Hadoop 2 often causes red security scans on Druid distribution because of the dependencies it brings. We want to move away from Hadoop 2 and provide Hadoop 3 distribution available. Switch druid to building with Hadoop 3 by default. Druid will still be compatible with Hadoop 2 and users can build hadoop-2 compatible distribution using hadoop2 profile.
Release note
Druid is now built with Hadoop 3. If you need Hadoop 2 compatible distribution, you can build one yourself using the source code and building a tar with hadoop2 profile.
