             Summary: Beeline outputs prompt+query on standard output when used in non-interactive mode
                 Key: HIVE-10202
                 URL: https://issues.apache.org/jira/browse/HIVE-10202
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Sergio Peña
            Assignee: Sergio Peña


When passing a SQL script file to Hive CLI, the prompt+query is not sent to the standard output nor standard error. This is totally fine because users might want to send only the query results to the standard output, and parse the results from it.

In the case of BeeLine, the promp+query is sent to the standard output causing extra parsing on the user scripts to avoid reading the prompt+query. 

Another drawback is in the security side. Sensitive queries are logged directly to the files where the standard output is redirected.

How to reproduce:
{noformat}
$ cat /tmp/query.sql 
select * 
from test
limit 1;

$ beeline --showheader=false --outputformat=tsv2 -u jdbc:hive2://localhost:10000 -f /tmp/query.sql > /tmp/output.log 2> /tmp/error.log

$ cat /tmp/output.log
0: jdbc:hive2://localhost:10000> select * 
. . . . . . . . . . . . . . . .> from test
. . . . . . . . . . . . . . . .> limit 1; 
451	451.713	false	y2dh7	["866","528","936"]
0: jdbc:hive2://localhost:10000>
{noformat}

We should avoid sending the prompt+query to the standard output/error whenever a script file is passed to BeeLine.
