             Summary: Used fixed/external version from hadoop jars in hdds/ozone projects
                 Key: HDDS-702
                 URL: https://issues.apache.org/jira/browse/HDDS-702
             Project: Hadoop Distributed Data Store
          Issue Type: New Feature
            Reporter: Elek, Marton
            Assignee: Elek, Marton


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 time).

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)
