-----------------------------------
Resolution: Duplicate
> impala-shell converts newlines to spaces in multi-line literals
> ---------------------------------------------------------------
>
> Key: IMPALA-1184
> URL: https://issues.apache.org/jira/browse/IMPALA-1184
> Project: IMPALA
> Issue Type: Bug
> Components: Clients
> Affects Versions: Impala 2.0
> Environment: I'm using the latest 2.0 build.
> Reporter: John Russell
> Priority: Minor
> Labels: impala-shell
>
> Now that impala-shell doesn't get confused by a line with an unbalanced
> single quote, I tried inserting a multi-line string literal. Looks like
> impala-shell normalizes all newlines (even inside string literals) to spaces
> before sending to the back end:
> [localhost:21000] > create table string_t (s string);
> [localhost:21000] > insert into string_t values ('hello
> > world');
> [localhost:21000] > select * from string_t;
> +-------------+
> | s |
> +-------------+
> | hello world |
> +-------------+
> I'm expecting behavior similar to MySQL, where even if the newline causes the
> query output to be formatted weirdly, it still preserves the newline:
> mysql> create table string_t (s varchar(64));
> Query OK, 0 rows affected (0.06 sec)
> mysql> insert into string_t values ('hello
> '> world');
> Query OK, 1 row affected (0.00 sec)
> mysql> select * from string_t;
> +-------------+
> | s |
> +-------------+
> | hello
> world |
> +-------------+
> 1 row in set (0.00 sec)
> When I cursor up in impala-shell, back to the INSERT...VALUES statement, the
> line-recalling code also turns the newline back into a space:
> [localhost:21000] > insert into string_t values ('hello world');
> MySQL's readline behavior is to only show that part of the line up to the
> newline:
> ...cursor up...
> mysql> world');
> ...cursor up...
> mysql> insert into string_t values ('hello
> They must be special-casing multi-line literals because if I split some other
> kind of statement over multiple lines, it does join them into one line when
> recalling the statement:
> mysql> create table
> -> foo (x int);
> Query OK, 0 rows affected (0.04 sec)
> ...cursor up...
> mysql> create table foo (x int);
