Hudson commented on YARN-3626: ------------------------------ FAILURE: Integrated in Hadoop-Hdfs-trunk #2125 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/2125/]) YARN-3626. On Windows localized resources are not moved to the front of the classpath when they should be.

On Windows this does not work > because the localized resources are not linked into their final location when > the classpath jar is created. To compensate for that localized jar resources > are added directly to the classpath generated for the jar rather than being > discovered from the localized directories. Unfortunately, they are always > appended to the classpath, and so are never preferred over system resources. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
