maxwellguo commented on CASSANDRA-15092:
----------------------------------------

ok, I will print the detailed information when the return code is not 200. the 
meta data for ecs(vm on alibaba cloud)'s localtion format is like 
:cn-hangzhou-a、us-east-a1 where, cn、us is just the name of the country , we 
devide the country into some region, like beijing , shanghai ,hangzhou which 
just represent some region id for the region that contain the city of 
beijing/shanghai/hangzhou, but the area is bigger than the city's area. they 
are just id for the regions. within the region, we divide the region into some 
smaller area ,just called a/b/c or a1/a2/b1/b2..., So under our snitch ,we use 
the region name  beijing/shanghai/hangzhou/east as the dc name , and the 
a/b/c/a1/b1/... the rack name.  So   the ECS of alibaba can be deploy over the 
world , the format of the ecs's metadata can just be called like the format 
described before.
