Description

• 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:

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"
