----------------------------------
Summary: Support -conf command line argument for picocli
Key: HDDS-1192
URL: https://issues.apache.org/jira/browse/HDDS-1192
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Elek, Marton
Assignee: Elek, Marton
org.apache.hadoop.hdds.GenericCli is the based class for all the Ozone related
command line application. It supports to define custom configuration variables
(-D or --set) but doesn't support the '--conf ozone-site.xml' argument to load
an external xml file to the configuration.
Configuration and OzoneConfiguration classes load the ozone-site.xml from the
classpath. But it makes very hard to start Ozone components in IDE as we can't
modify the classpath easily.
One option here is to support the --conf everywhere to make it possible to
start ozone cluster in the IDE.
Note: It's a nice to have for 0.4.0. I marked it as 0.5.0 but safe to commit at
anytime to 0.4.0
