    Description

      While we are trying to run hadoop archive tool in widows using this way, it is giving the below exception.

      java org.apache.hadoop.tools.HadoopArchives -archiveName temp.har D:/test/in E:/temp

       
      
      java.lang.NullPointerException
      	at org.apache.hadoop.tools.HadoopArchives.writeTopLevelDirs(HadoopArchives.java:320)
      	at org.apache.hadoop.tools.HadoopArchives.archive(HadoopArchives.java:386)
      	at org.apache.hadoop.tools.HadoopArchives.run(HadoopArchives.java:725)
      	at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
      	at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79)
      	at org.apache.hadoop.tools.HadoopArchives.main(HadoopArchives.java:739)
      
      

      I see the code flow to handle this feature in windows also,

      Path.java
      /** Returns the parent of a path or null if at root. */
        public Path getParent() {
          String path = uri.getPath();
          int lastSlash = path.lastIndexOf('/');
          int start = hasWindowsDrive(path, true) ? 3 : 0;
          if ((path.length() == start) ||               // empty path
              (lastSlash == start && path.length() == start+1)) { // at root
            return null;
          }
          String parent;
          if (lastSlash==-1) {
            parent = CUR_DIR;
          } else {
            int end = hasWindowsDrive(path, true) ? 3 : 0;
            parent = path.substring(0, lastSlash==end?end+1:lastSlash);
          }
          return new Path(uri.getScheme(), uri.getAuthority(), parent);
        }
