             Summary: Unable to CTRL+C an unfinished query in impala-shell
                 Key: IMPALA-9036
                 URL: https://issues.apache.org/jira/browse/IMPALA-9036
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
            Reporter: Gabor Kaszab


When the query prompts after a line break it doesn't accept CTRL+C to cancel typing that query. Instead it waits for the user to terminate the query.
{code:java}
default> select * from random_table
                         > ^C
                         > ^C
                         > ^C
                         > ^C
                         > ^C
                         > ^C
                         > ;
{code}
In this case it's easy to terminate as only a ';' is needed but if the user messes up a complicated query involving multiple single qouotes, double quotes and their escaped versions then it might be difficult to find out what is missing and they won't be able to simply CTRL+C and start over.

Note, without a line break in the query CTRL+C works fine:

{code:java}
default> select * from random_table^C
default>
{code}
