Uma Maheswara Rao G commented on HADOOP-10520:
----------------------------------------------
Thanks a lot Liu, for the patch update. Latest patch almost looks good to me.
Worth having flag explanation in XattrSetFlag docs.
Also please mention that setXAttrs with out specifying flag will create
attribute if does not exist as well.
Note: Linux has listxattr api which will list the xattrs names. Since we have
an API getXattrs which will return map with name and value, we are good with
that. So, we thought of not having any extra api for that now. I discussed
with Alejandro offline regarding this point and we are in this conclusion.
> Extended attributes definition and FileSystem APIs for extended attributes.
