Doroszlai, Attila commented on HDDS-1351:
-----------------------------------------
[~xyao], try eg. the {{ozones3}} jdk8-based compose file to reproduce the issue.
However, you are right, jdk11 makes it worse, because with that {{jaxb-api}} is
missing, and it fails even earlier:
{code:title=docker exec ozone_datanode_1 ozone genconf /tmp}
Error: Unable to initialize main class
org.apache.hadoop.ozone.genconf.GenerateOzoneRequiredConfigurations
Caused by: java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
{code}
