Chris Nauroth updated HADOOP-9290:
----------------------------------
Attachment: HADOOP-9290.3.patch
Thanks for the reviews, Arpit and Ivan. I'm attaching version 3 of the patch.
This still might not be the final version, but I wanted to get you something to
add the comment and fix the contrib problem ASAP.

It seems that the currently defined value for LD_LIBRARY_PATH is invalid.
{quote}
I think the current values are correct, and my test runs on Linux were
successfully loading libhadoop.so. On Windows, the build puts hadoop.dll into
target/bin. On Linux, the build puts libhadoop.so into
target/native/target/usr/local/lib.

hadoop-project/pom.xml: Assuming that we specified a valid value for
LD_LIBRARY_PATH above, the following section might not be needed
{quote}
I think we need a separate definition for PATH, because Windows doesn't use
LD_LIBRARY_PATH, right? Perhaps the split of definitions between the main part
of the pom.xml and the native-win profile is a bit confusing. I'll see if I
can do anything to improve that.

Might make sense to either remove hadoop.common.build.dir or use it for both
winutils.exe and hadoop.dll
{quote}
My goal with hadoop.common.build.dir was to prevent the need for child modules
to duplicate the whole maven-surefire-plugin <configuration> stanza. I had
forgotten that we already started down that path for HADOOP_HOME. I think I
can simplify so that the hadoop.common.build.dir override handles both needs,
and there is less pom.xml configuration to maintain in child modules. I'll
test this and report back.
