             Summary: Generated configs missing from ozone-filesystem-lib jars
                 Key: HDDS-2250
                 URL: https://issues.apache.org/jira/browse/HDDS-2250
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: build, Ozone Filesystem
            Reporter: Attila Doroszlai
            Assignee: Attila Doroszlai


Hadoop 3.1 and 3.2 acceptance tests started failing with HDDS-1720, which added 
a new, annotated configuration class.

The [change itself|https://github.com/apache/hadoop/pull/1538/files] looks 
fine.  The problem is that the packaging process for {{ozone-filesystem-lib}} 
jars keeps only 1 or 2 {{ozone-default-generated.xml}} files.  With the new 
config in place, client configs are missing, so Ratis client gets evicted 
immediately due to {{scm.container.client.idle.threshold}} = 0.  This results 
in NPE:
