-------------------------------------
{quote}Are we intending to emulate java behavior for the -D system
properties?{quote}
I don't believe we are. I'm specifically trying to match the behavior of the
hbase shell prior to HBASE-24772. in our prior release we expressly did try to
support args that look like {{-D prop=value}}. I believe this was introduced in
HBASE-21567.
It's not stated anywhere in that jira, but it looks to me like it's trying to
match the config definition handling from [hadoop generic cli
args|https://hadoop.apache.org/docs/r3.3.1/hadoop-project-dist/hadoop-common/CommandsManual.html#Generic_Options]
ala Hadoop's
[ToolRunner|https://hadoop.apache.org/docs/r3.3.1/api/org/apache/hadoop/util/ToolRunner.html].
Which makes sense given our project background.
