----------------------------------------

bq. Maybe retain + deprecate?

OK, sounds like a good safe plan.

> If {{winutils.exe}} can't be found {{HADOOP_HOME}} wrong/unset or other causes, then
an error is logged -but when any of the {{Shell}} operations are used, an NPE is raised rather
than something meaningful.
> The error message at setup time should be preserved and then raised before any attempt
to invoke a winutils-driven process made
