Akira AJISAKA commented on HDFS-8462:
-------------------------------------
Thanks [~jagadesh.kiran] for taking this issue. Some comments:
{code:title=FSImageLoader#getXAttrs}
* @return JSON formatted ListXAttrs
{code}
1. Would you change {{ListXAttrs}} to {{XAttrs}}?
(http://hadoop.apache.org/docs/r2.7.0/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#XAttrs_JSON_Schema)
{code:title=FSImageLoader#listXAttrs}
* @return JSON formatted ListXAttrs
{code}
2. Would you change {{ListXAttrs}} to {{XAttrNames}}?
(http://hadoop.apache.org/docs/r2.7.0/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#XAttrNames_JSON_Schema)
3. For testing these operation, would you create an {{WebHdfsFileSystem}}
instance and call {{getXAttr}}, {{getXAttrs}}, and {{listXAttrs}} as
{{TestOfflineImageViewerForAcl}}?
> Implement GETXATTRS and LISTXATTRS operation for WebImageViewer

>
> In Hadoop 2.7.0, WebImageViewer supports the following operations:
> * {{GETFILESTATUS}}
> * {{LISTSTATUS}}
> * {{GETACLSTATUS}}
> I'm thinking it would be better for administrators if {{GETXATTRS}} and
> {{LISTXATTRS}} are supported.
