Yi Liu commented on HDFS-6258:
------------------------------

Thanks all.
I have split the patch to several sub-JIRAs, and will attach updated patches 
which include all review comments to those sub-JIRAs. Andrew, Chris and Uma, 
please help to review them:

HDFS-6299: Protobuf for XAttr and client-side implementation 
HDFS-6298: XML based End-to-End test for getfattr and setfattr commands
HDFS-6301: NameNode: persist XAttrs in fsimage and record XAttrs modifications 
to edit log.
HDFS-6302: Implement XAttr as a INode feature.
HDFS-6303: HDFS implementation of FileContext API for XAttrs.

This JIRA will become "implement the server-side storage". 
Charles, please generate your patch for javadoc in those sub-JIRAs, thanks.
