----------------------------------
Summary: When pressing Ctrl+C the content of the shell history
gets doubled
Key: IMPALA-9398
URL: https://issues.apache.org/jira/browse/IMPALA-9398
Project: IMPALA
Issue Type: Bug
Components: Clients
Affects Versions: Impala 3.3.0
Reporter: Adam Tamas
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.
