Elek, Marton commented on HDDS-2121:
------------------------------------
Thanks to open this issue [~arp]
1. HDDS-2120 removes the included hadoop classes from the current jar (yes,
it's very short, so it also can be merged to this one)
2. I agree with the idea: we can shade (package relocate) all the remaining 3rd
party classes inside current to be sure they are not conflicting.
ps: legacy jar still required to support older version of spark/hadoop (if we
would like to support them...)

> Key: HDDS-2121
> URL: https://issues.apache.org/jira/browse/HDDS-2121
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: build
> Reporter: Arpit Agarwal
> Priority: Blocker
>
> We need a shaded Ozonefs jar that does not include Hadoop ecosystem
> components (Hadoop, HDFS, Ratis, Zookeeper).
> A common expected use case for Ozone is Hadoop clients (3.2.0 and later)
> wanting to access Ozone via the Ozone Filesystem interface. For these
> clients, we want to add Ozone file system jar to the classpath, however we
> want to use Hadoop ecosystem dependencies that are `provided` and already
> expected to be in the client classpath.
> Note that this is different from the legacy jar which bundles a shaded Hadoop
> 3.2.0.
