> If Ctrl+C was pressed in the impala-shell, the content of the ~/.impalahistory got copied into the end of the file for each instance the Ctrl+C was pressed.
> The new queries written while the shell was open is not duplicated and the file is only updated after the impala-shell was closed.
> Example:
> $ rm ~/.impalahistory
> $ impala-shell.sh
> impala> select 1; 
> impala> select 2; 
> impala> quit;
> $ cat -n ~/.impalahistory
>  1 select 1;
>  2 select 2;
>  3 quit;
> $ impala-shell.sh
> impala> ^C
> impala> quit;
> $ cat -n ~/.impalahistory
>  1 select 1;
>  2 select 2;
>  3 quit;
>  4 select 1;
>  5 select 2;
>  6 quit;
> The second impala-shell session, Ctrl-C doubled all the history entries.
