Steve Loughran commented on HADOOP-10775:
-----------------------------------------
I was reluctant to pull any methods as there is a risk they are in use
elsewhere —this class may have been tagged as internal, but its been used
enough (including the DistributedShell) example, that it's in use. Maybe retain
+ deprecate?
bq. Since this patch essentially removes the Java 6 symlink workaround special
path, shall we change SymlinkBaseTest and TestSymlinkLocalFS to remove the
emulatingSymlinksOnWindows checks?

> 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
