Tim Armstrong updated IMPALA-5048:
----------------------------------
Issue Type: Improvement (was: Bug)
> Change integer types for number of rows / tuples and memory sizes to 64bit
> --------------------------------------------------------------------------
>
> Key: IMPALA-5048
> URL: https://issues.apache.org/jira/browse/IMPALA-5048
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 2.9.0
> Reporter: Lars Volker
> Assignee: Lars Volker
> Priority: Major
>
> * We recently found several issues with integer overflows: IMPALA-4995,
> IMPALA-4997, IMPALA-5021. To reduce the likelihood of similar issues we
> should make sure that all variables which store either a number of rows,
> number of tuples, or a number of bytes are of type int64_t.
> Here are some useful commands to find candidates:
> {noformat}
> git grep -E "^ +int(|32_t) .*row"
> git grep -E "^ +int(|32_t) .*tuple"
> git grep -E "^ +int(|32_t) .*num_"
> git grep -E "^ +int(|32_t) .*bytes"
> git grep -E "^ +int(|32_t) .*size"
> {noformat}
