Re: Configuring SPNEGO

This is normal behavior as you have to authenticate with kerberos on your client and negotiate kerberos with your browser.

On the local host, where web browser is running: 1. Configure krb5.conf with correct hadoop domain info. 2. Run kinit to obtain a kerberos ticket from KDC server. 3. Configure web browser to use the kerberos ticket, which depends on different type of web browser (More details on http://crimsonfu.github.io/2012/06/22/kerberos-browser.html).
