Colin Patrick McCabe commented on HDFS-3753:
--------------------------------------------
Thanks, Eli. These kind of environment setup issues are exactly what the test
was meant to catch, and it looks like they have.
> Tests don't run with native libraries

> Key: HDFS-3753
> URL: https://issues.apache.org/jira/browse/HDFS-3753
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: build, test
> Affects Versions: 2.0.0-alpha
> Reporter: Eli Collins
> Assignee: Colin Patrick McCabe
> Fix For: 2.0.3-alpha
>
> Attachments: HDFS-3753.001.patch, HDFS-3753.002.patch

> 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.
