---------------------------------

             Summary: The error message is not friendly when ranger plugin service  cannot
be connected
                 Key: HAWQ-1276
                 URL: https://issues.apache.org/jira/browse/HAWQ-1276
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: Security
            Reporter: Xiang Sheng
            Assignee: Ed Espino
             Fix For: 2.2.0.0-incubating


The error message is not friendly when RPS cannot be connected.

We expect a more clear message printed out, for example, "cannot connect to RPS service: host/port/service
 ".

What's more, there are many other error and log messages and log level should be refined to
more friendly. Some unused log should be removed. 

```

psql (8.2.15)
Type "help" for help.
