For Knox , you have to make 2 curl calls. The second curl call should be made to the "Location" header obtained from the 1st curl call response.

1st curl call

curl -i -k -u admin:admin-password -X GET 'https://localhost:8443/gateway/default/webhdfs/v1/tmp/uname.txt?op=OPEN'
HTTP/1.1 307 Temporary Redirect

2nd curl call (url is taken from Location header obtained in 1st curl call)

curl -i -k -u admin:admin-password -X GET https://hadoop1:8443/gateway/default/webhdfs/data/v1/webhdfs/v1/tmp/uname.txt?_=AAAACAAAABAAAACgLvtI...
