Re: curl with hive on secured cluster

Usually when you want to use curl in combination with Kerberos (secured cluster), you have to use the following command:

curl --negotiate -u : -X GET 'http://localhost:50111/templeton/v1/hive?user.name=ekoifman'

Make sure you have a valid kerberos ticket (run: klist)

I generally add "-b ~/cookie.txt -c ~/cookie.txt" also the curl command. And "-i" will give addition information also.

curl --negotiate -u : -b ~/cookie.txt -c ~/cookie.txt ...

"localhost" doesn't work with kerberos authentication, you need the actual hostname in URL. @Jonas Straub can you please edit ?

Thanks @Jonas Straub @bdurai for your comments.

In user.name what value should I pass? is it a kerberos principal of the user who is the executing the command

This is what I got after I ran the above command.

~> curl --negotiate -u : -X GET 'http://WebdhcatserverDNS:50111/templeton/v1/hive?user.name=ekoifman' {"error":null}:~> curl --negotiate -u : -X GET 'http://WebhcatserverDNS:50111/templeton/v1/hive?user.name=ekoifman

User.name would be ignored during kerberos mode. The credentials via kinit is what gets used.
