Hi, I am bit confused on Security part of Hadoop. Cluster is behind the firewall. I have read that Hadoop can be configured with LDAP also. I want to know which is better : configure Hadoop security with LDAP or Kerberos as both provide authentication.
Please provide me more details on this as I am newbee in this part.
