             Summary: Ozone: fix classpath of yarn components
                 Key: HDFS-13302
                 URL: https://issues.apache.org/jira/browse/HDFS-13302
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: HDFS-7240
    Affects Versions: HDFS-7240
            Reporter: Elek, Marton
            Assignee: Elek, Marton


HDFS-13258 introduced a separated classpath for hdsl/cblock/ozone components.

The reason is the behaviour of the dist-layout-stitching. The internal copy command in the dist-layout-stitching copies the jar files only if they don not exist in any of the existing subfolder of the share/hadoop directory.

With the new separated classpath if some of the dependencies are already copied to share/hadoop/hdsl or share/hadoop/ozone, they won't be copied to the share/hadoop/yarn directory and won't be added to the classpath. (as the hdsl copy is before the yarn copy commands)

Could be fixed easily with moving the ozone/cblock/hdsl related stuff to the end of the dist-layout-stitching.
