org.apache.hadoop.nfs.nfs3.response.WccAttr
SetAttr3 contains the file attributes that can be set from the client. The fields are the same as the similarly named fields in the NFS3Attributes structure.

        entries[i] = new READDIRPLUS3Response.EntryPlus3(fileId,
            fstatus[i].getLocalName(), fileId, attr, childHandle);
