> Components: util
> Affects Versions: trunk-win, 2.7.1
> Environment: windows
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor

> 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
