Review comment:
Yes, this is a part of the generic option for the Hadoop tool and isn't
option for Java command itself
https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/CommandsManual.html#Generic_Options
ToolRunner internally process this sort of common options in
GenericOptionsParser
https://github.com/apache/hadoop/blob/07627ef19e2bf4c87f12b53e508edf8fee05856a/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/util/GenericOptionsParser.java#L50-L112
