> Test execution when run with the native flag and native libraries have been built don't
actually use the native libs because NativeCodeLoader is unable to load native-hadoop. Eg
run {{mvn compile -Pnative}} then {{mvn -Dtest=TestSeekBug test -Pnative}} and check the test
output. This is because the test's java.library.path is looking for the lib in hdfs (
> hadoop-hdfs-project/hadoop-hdfs/target/native/target/usr/local/lib) however the native
lib lives in common. I confirmed copying the lib to the appropriate directory fixes things.
We need to update the java.library.path for test execution to include the common lib dir.
 This may be an issue with MR as well.
