Subject [jira] [Created] (YARN-2719) Windows: Wildcard classpath variables not expanded against resources contained in archives
Date Tue, 21 Oct 2014 16:00:38 GMT
Craig Welch created YARN-2719:
---------------------------------

             Summary: Windows: Wildcard classpath variables not expanded against resources
contained in archives
                 Key: YARN-2719
                 URL: https://issues.apache.org/jira/browse/YARN-2719
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Craig Welch
            Assignee: Craig Welch


On windows there are limitations to the length of command lines and environment variables
which prevent placing all classpath resources into these elements.  Instead, a jar containing
only a classpath manifest is created to provide the classpath.  During this process wildcard
references are expanded by inspecting the filesystem.  Since archives are extracted to a different
location and linked into the final location after the classpath jar is created, resources
referred to via wildcards which exist in localized archives  (.zip, tar.gz) are not added
to the classpath manifest jar.  Since these entries are removed from the final classpath for
the container they are not on the container's classpath as they should be.
