Thank You, [~elek] for info. Ya when we compile with -am and pl options no need to specify

+1 LGTM.

Patch is not applying to trunk. It needs a rebase.

Patch is not applying to trunk. We can commit with current patch also, as the issue is with
one empty line in hadoop-project/pom.xml.

> In the current form of the project ozone uses the in-tree snapshot version of the hadoop
(hadoop 3.3.0-SNAPSHOT as of now).
> I propose to use a fixed version from the hadoop jars which could be independent from
the in-tree hadoop.
> 1. With using already released hadoop (such as hadoop-3.1) we can upload the ozone jar
files to the maven repository without pseudo-releasing the hadoop snapshot dependencies. (In
the current form it's not possible without also uploading a custom, ozone flavour of hadoop-common/hadoop-hdfs)
> 2. With using fixed version of hadoop the build could be faster and the yetus builds
could be simplified (it's very easy to identify the projects which should be checked/tested
if only the hdds/ozone projects are part of the build: we can do full build/tests all the
> After the previous work it's possible to switch to fixed hadoop version, because:
> 1) we have no more proto file dependency between hdds and hdfs (HDDS-378, and previous
works by Mukul and Nanda)
> 2) we don't need to depend on the in-tree hadoop-project-dist (HDDS-447)
