a question about webhdfs

[douxin]

hi guys,

   I am using webhdfs, and I noticed that when I exec this:
   "curl -i -L
   
'http://192.168.1.217:50070/webhdfs/v1/user/hadoop/sample.txt?op=GETFILECHECKSUM'"

   It is redirected to
   "http://hadoop2:50075/webhdfs/v1/user/hadoop/sample.txt?op=GETFILECHECKSUM";

   I am wondering why the redirected url used hostname instead of an IP
   of it?
   how can I set it so that the url will use an IP?

   Cheers,
   Dou
