isKerberosEnabled

public static boolean isKerberosEnabled(org.apache.hadoop.conf.Configuration conf)

Check if Kerberos authentication is enabled. This is used by: - LLAP daemons - Tez AM - HS2 - LLAP status service Among the these Tez AM process has the lowest security setting wrt Kerberos in UGI. Even in secure scenarios Tez AM will return false for UGI.getLoginUser().hasKerberosCredentials() as it does not log in using Kerberos. Hence UGI.isSecurityEnabled() is the tightest setting we can check against.
