Subject [jira] [Created] (HDDS-95) Shade the hadoop-ozone/objectstore-service project
Date Tue, 22 May 2018 17:10:00 GMT
Elek, Marton created HDDS-95:

             Summary: Shade the hadoop-ozone/objectstore-service project
                 Key: HDDS-95
                 URL: https://issues.apache.org/jira/browse/HDDS-95
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Elek, Marton

Ozone has datanode plugin (hadoop-hdds/container-service) which is activated as a datanode
service plugin (dfs.datanode.plugins=org.apache.hadoop.ozone.HddsDatanodeService)

Also HddsDatanodeService plugin will use hadoop-ozone/object-store service component (configured
by hdds.datanode.plugins=org.apache.hadoop.ozone.web.OzoneHddsDatanodeService).

The goal is to shade all the required classes two one jar file (objectstore-service + all
the dependencies). If the jar will be added to the classpath of any hadoop cluster (let's
say 3.0 or 3.1) it should be started without any conflict in the classes (ozone uses hadoop
trunk where hadoop common could be newer).
