Description

Impala uses Ctrl+C to cancel a running query, which works. However, running Ctrl+C for a non-running query does not work. Example:

[localhost:21000] default> abcde (press ctrl+c) --> this does not do anything

Compare this behavior to Linux shell.

$ abcde^C --> this cancel the statement and start a new one prompt
$
