Description

In http://hadoop.apache.org/docs/current/hadoop-auth/Examples.html, there is "curl --negotiate -u foo -b ~/cookiejar.txt -c ~/cookiejar.txt http://localhost:8080/hadoop-auth-examples/kerberos/who". A better way is to use "-u :" instead of "-u foo". With the use of the former option, curl will not prompt for a password.
