Project: Ranger
Issue Type: New Feature
Components: admin
Reporter: Qiang Zhang

In real business environment, such as banks application and so on, we should
use other Ranger service to continuely supply service once a Ranger service
exits abnormally. We call the feature as high availability. The Ranger high
availability includes:
1. The Ranger admin is high availability;
2. The mysql service that saves meta data is high availability.
For the Ranger admin high availability our scheme is as following:
1. Add a configuration item in plugin. The configuration item includes two the
address of the Ranger admin service.
2. The plugin refreshed policy from other Ranger admin service once it refresh
policy from a Ranger admin service fail.
For the mysql service that saves meta data admin high availability, our scheme
is as following:
1. Add a configuration item in the Ranger admin. The configuration item
includes two the address of the mysql service.
2. Build two jdbc connection pools. The other will be used once a jdbc
connection fail.
