 Hi： 
    karan， singh. First of all thank you so  much for  replying and giving your precious time to this problem!
I tried repeat steps 2, 4 and 5 in by executing them with --nameclient.radosgw-us-west-1. and the case has progressed a lot。(below are some the  logs)

I am now getting

Hi: all

when I Configuring Federated Gateways， I got  the error as below:

sudo radosgw-agent  -c  /etc/ceph/ceph-data-sync.conf  
ERROR:root:Could not retrieve region map from destination

 You should check that the region map is correct , especially the endpoints. Make sure firewall is not blocking the way between RGW instances.

Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/radosgw_agent/cli.py", line 269, in main
    region_map = client.get_region_map(dest_conn)

Cross verify the key

I  have some quesions when I execute the command 
1、radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.us-west-1
i  have no idea about the option --name ,   what's the difference  if  i  do it without --name config;

—name us used to supply ceph user name that should be used to run radosgw-admin command against. Default is client.admin , if client.admin keyring are not present you need to supply another user with —name option to run Ceph commands. 

2、Create a Region
there is a conversation near the end of doc :
   If you use different Ceph Storage Cluster instances for regions, you should repeat steps 2, 4 and 5 in by executing them with --nameclient.radosgw-us-west-1. You may also export the region map from the initial gateway instance and import it followed by updating the region map. 

I has one cluster named ceph, one region named us, and two zones: us-east、 us-west， us-east is the  master  zone. I has two gateway instances：client.radosgw.us-east-1、client.radosgw.us-west-1.  Do i need repeat steps 2,4,and 5? do  i need export the region map from the  initial gateway instance and import it 

If you have 2 Different Ceph Cluster then only you should do this.  I assume you have only 1 Ceph cluster with 1 region and 2 zones and 2 gateway instances , then you need not to repeat those steps.
