     [ https://issues.apache.org/jira/browse/HADOOP-9290?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chris Nauroth updated HADOOP-9290:
----------------------------------

    Attachment: HADOOP-9290.2.patch

Here is a patch that allows a child pom.xml to override the relative path to hadoop-common's build dir for finding the native library.  I tried running various tests in hadoop-common, hadoop-mapreduce-client-jobclient, hadoop-yarn-server-nodemanager, and hadoop-yarn-applications-distributedshell.  I repeated running the tests from the root of the repository and also the individual child modules.  I repeated this procedure on both Windows and Linux with native build.  In all cases, I saw the tests successfully load the native library.

> Some tests are unable to load the native DLL on Windows. The culprit appears to be an incorrect PATH configuration for the native-win profile in hadoop-project/pom.xml.
