I am trying to secure Hadoop environment installed in windows. So basically I started to analyse how to secure a Unix-based hadoop cluster. Have gone through various links related to Kerberos and other Apache Add-ons(Knox/ Rhino/ Sentry).. Yet to check each one of them,
In the mean time, found Active Directory which is about User Management(LDAP). Also it seems AD has Kerberos installed in it by default. So if AD contains LDAP and Kerberos with itself, cant we use Active Directory alone to secure hadoop cluster?
All these Google suggestions Links, suggests a framework to secure any one of the company's pre formed Unix-based hadoop cluster as,
Authorization - Active Directory(LDAP),
Authentication - Kerberos
To come again, My question is cant we use Active Directory alone to secure a hadoop cluster?
