Ismaël Mejía commented on BEAM-3581:
------------------------------------
I didn't say the system properties caused the issue, I said that this command
allows to reproduce it at least in my linux machine. If i run just the test
BeamSqlNonAsciiTest it passes normally.
> [SQL] Support for Non-ASCII chars is flaky

> Key: BEAM-3581
> URL: https://issues.apache.org/jira/browse/BEAM-3581
> Project: Beam
> Issue Type: Bug
> Components: dsl-sql
> Reporter: Anton Kedin
> Assignee: Anton Kedin
> Priority: Major
>
> Beam SQL overrides default charset that Calcite uses and sets it to UTF16. It
> is done via system properties.
> Problem is that we do this only when it hasn't been set yet. So if system
> property has been set to ISO-8859-1 (Calcite's default), then test runs will
> fail when trying to encode characters not supported in that encoding.
> Solution:
> - because it's a system property, we don't want to force override it;
> - for the same reason we cannot set it for a specific query execution;
> - we can expose a static method on BeamSql to override these properties if
> explicitly requested;
> - affected tests will explicitly override it;
> - otherwise behavior will stay unchanged and we will respect defaults and
> user settings;
