> Ranger Admin installation fails when using MariaDB/MySQL with binary logging enabled.
> The install should work even if binary logging is enabled.
> *Problem Statement:* Currently MySQL DB patch 007 and 008 is having MySQL UDF functions
which are not DETERMINISTIC
> When you create a stored function, you must declare either that it is deterministic or
that it does not modify data. Otherwise, it may be unsafe for data recovery or replication.
> By default, for a CREATE FUNCTION statement to be accepted, at least one of DETERMINISTIC,
NO SQL, or READS SQL DATA must be specified explicitly. Otherwise, an error occurs: 
> {code:java}
> ERROR 1418 (HY000): This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA
in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators
variable)
> {code}
> Although it is possible to create a deterministic stored function without specifying
DETERMINISTIC, you cannot execute this function using statement-based binary logging. To execute
such a function, you must use row-based or mixed binary logging. Alternatively, if you explicitly
specify DETERMINISTIC in the function definition, you can use any kind of logging, including
statement-based logging.
> To relax the preceding conditions on function creation (that you must have the SUPER
privilege and that a function must be declared deterministic or to not modify data), set the
global log_bin_trust_function_creators system variable to 1. By default, this variable has
a value of 0, but you can change it like this: 
> {code:java}
> SET GLOBAL log_bin_trust_function_creators = 1;
> {code}
> If binary logging is not enabled, log_bin_trust_function_creators does not apply. SUPER
is not required for function creation unless, as described previously, the DEFINER value in
the function definition requires it.
> *Proposed Solution:* We can remove usage of stored function and it can be replaced with
the stored procedure.
