Qiang Zhang updated RANGER-1293:
--------------------------------
Description:
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.

In the MysqlConf class of security-admin/scripts/dba_script.py, the
create_rangerdb_user and grant_xa_db_user function have following problem:
At the beginning the hosts_arr variable was set ["%", "localhost"] as default
