[jira] [Created] (HADOOP-11406) xargs -P is not portable

Allen Wittenauer created HADOOP-11406:
-----------------------------------------

             Summary: xargs -P is not portable
                 Key: HADOOP-11406
                 URL: https://issues.apache.org/jira/browse/HADOOP-11406
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 3.0.0
            Reporter: Allen Wittenauer
            Priority: Critical


hadoop-functions.sh uses xargs -P in the ssh handler.  -P is a GNU extension and is not available on all operating systems.  We should add some detection for support and perform an appropriate action.
