------------------------------------

             Summary: NameNode to support file path prefix /.reserved/bypassExtAttr
                 Key: HDFS-12295
                 URL: https://issues.apache.org/jira/browse/HDFS-12295
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs, namenode
            Reporter: Yongjun Zhang
            Assignee: Yongjun Zhang


Let NameNode to support prefix /.reserved/bypassExtAttr, so client can add thisprefix to a path before calling getFileStatus, e.g. /ab/c becomes /.reserved/bypassExtAttr/a/b/c. NN will parse the path at the very beginning, and bypass external attribute provider if the prefix is there.
