Steve Loughran updated HADOOP-10775:
------------------------------------
Attachment: HADOOP-10775.patch
As well as retaining the original {{WINUTILS}} field, which is null if the
field could not be retrieved, I've added two methods {{getWindowsU
# {{getWinutilsPathStrict()}} raises an IOE
# {{getWinutilsPathRTE()}} raises an RTE: I've inserted this where the method
calling it doesn't raise an IOE.
Both these will throw an exception which nests the exception caught when trying
to set up the path; those also include, on windows a link to a new wiki page.
* The wiki entry is [[https://wiki.apache.org/hadoop/WindowsProblems]]
* It links to a repo where we can collect the windows binaries. Currently
[[mine|https://github.com/steveloughran/winutils]]
I've not been through all references to Shell.WINUTILS; the ones where a path
is set up but not executed are left alone (e.g.
{{Shell.getSetPermissionCommand()}}. Instead I fixed Shell Executor to scan
command for null entries and fail fast, with better text.
Irrespective of what jenkins says, this patch needs to be tested against a
windows host
> Shell operations to fail with meaningful errors on windows if winutils.exe

> 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
