-----------------------------------
Summary: impala-shell accepts very big numbers but fails to store
them correctly
Key: IMPALA-12035
URL: https://issues.apache.org/jira/browse/IMPALA-12035
Project: IMPALA
Issue Type: Bug
Reporter: Bakai Ádám
I tried to insert rows very big bigints, and it worked as expected with big
integers (error message, no new row stored), but it didn’t work as expected
with ridiculously big integers( no error message, stored incorrect value). Here
are the commands used:
{code:java}
drop TABLE my_first_table2;
CREATE TABLE my_first_table2
(
id BIGINT,
name STRING,
PRIMARY KEY(id)
);
INSERT INTO my_first_table2 VALUES (cast(9 as BIGINT), "sarah");
-- this works just fine as expected
INSERT INTO my_first_table2 VALUES (cast(9999999999999999999999 as BIGINT),
"sarah");
-- ERROR: UDF ERROR: Decimal expression overflowed which is expected since it
is over bigint max value (source:
https://impala.apache.org/docs/build/plain-html/topics/impala_bigint.html#:~:text=Range%3A%20%2D9223372036854775808%20..,9223372036854775807.
)
INSERT INTO my_first_table2 VALUES
(cast(999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999
as BIGINT), "sarah");
-- this succeeds and doesn't throw the same error as the previous command which
is concerning
select * from my_first_table2;
-- there are two rows in the table, and the id is incorrect in one of them
{code}
