[jira] [Created] (HDFS-6464) Add xattr.names parameter for WebHDFS getXAttrs.

Yi Liu created HDFS-6464:
----------------------------

             Summary: Add xattr.names parameter for WebHDFS getXAttrs.
                 Key: HDFS-6464
                 URL: https://issues.apache.org/jira/browse/HDFS-6464
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 3.0.0
            Reporter: Yi Liu
            Assignee: Yi Liu
             Fix For: 3.0.0


For WebHDFS getXAttrs through names, right now the entire list is passed to the client side and then filtered, which is not the best choice since it's inefficient and precludes us from doing server-side smarts on par with the Java APIs. 
Furthermore, if some xattrs doesn't exist, server side should return error.
