I have read the article about fine grain security Spark Thrift Server with llap. It works correctly, but when I connect to Spark Thrift Server using beeline, I just login with user and without password or what I am missing here. I curious that, with this method, anyone can login without password set. Can I set password for each user or have any method to authenticate user before user can execute query.
If cluster is not secured / kerberized and you have not configured any alternative authentication method like ldap then this is exactly what you will experience. You should consider securing your cluster by using kerberos authentication. You can enable kerberos using ambari.
