Summary: Harden long string testing
Key: IMPALA-12569
URL: https://issues.apache.org/jira/browse/IMPALA-12569
Project: IMPALA
Issue Type: Sub-task
Components: Backend, Infrastructure
Reporter: Zoltán Borók-Nagy
With small string optimization [~csringhofer] pointed out that most of our test
data have small strings. And new features are typically tested on the existing
test tables (e.g. alltypes that only have small strings), or they add new tests
with usually small strings only. The latter is hard to prevent. Therefore the
long strings might have less test coverage if we don't pay enough attention.
To make the situation better, we could
# Add long string data to the string column of alltypes table and
complextypestbl and update the tests
# Add backend flag the makes StringValue.Smallify() a no-op, and create a test
job (probably with an ASAN build) that runs the tests with that flag turned on.
