> There were logic errors in create_rangerdb_user and grant_xa_db_user function.
> The reason for the error is that the hosts_arr variable was set ["%", "localhost"] as
default value at the beginning. The hosts_arr variable will include two localhost values if
self.host equal to localhost. As a result, the back code block will be executed repeatedly,
the performance of the program will be reduced. The error code is following:
> hosts_arr =["%", "localhost"]
> hosts_arr.append(self.host)
> for host in hosts_arr:
>     business logic code block
> From the above code logic we can be seen that the business logic code block will be repeated
twice when the db_host attribute is set to localhost in install.properties.
