Chris Nauroth commented on HADOOP-8933:
---------------------------------------
Currently, I see this problem on Mac OS X due to native code incompatibilities,
like HADOOP-7147.
The root cause is that when the script pre-builds the existing trunk code, it
does not use -Pnative, but when it builds after applying the patch, it does use
-Pnative. Note that we don't want to remove -Pnative completely, because that
was added to fix a bug reported in HADOOP-8488. Instead, if we provided an
additional optional flag for developers to disable the native portion of the
build, then it would still catch problems in the native code by default, but
developers on non-compatible platforms would still have a way to use
test-patch.sh as long as they are not working on the native code.
> test-patch.sh fails erroneously on platforms that can't build native

> If a developer is working on a platform that can't build native (like OS X
> right now), then test-patch.sh will report the patch as a failure due to "The
> patch appears to cause the build to fail." This is incorrect, because the
> developer's patch didn't cause the build to fail. Adding an extra optional
> flag to test-patch.sh would help developers on these platforms.
