--------------------------------------
Summary: CSV-related tests may fail depending on locale
Key: FLINK-3353
URL: https://issues.apache.org/jira/browse/FLINK-3353
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.0.0
Reporter: Stefano Baghino
Assignee: Stefano Baghino
Priority: Trivial
Fix For: 1.0.0
As I've been running some tests, three suites
({{KMeansWithBroadcastSetITCase.java}}, {{ScalaCsvReaderWithPOJOITCase.scala}}
and {{CsvReaderITCase.java}}) kept failing locally because the expected results
(string literals) were matched against an object rendered as a string using the
{{String.format}} method, a method whose result depends on the default Locale;
as my Locale (Italian) renders doubles with a comma instead of a dot as the
decimal separator, the representation of doubles diverged from the expected
one, thus making my tests fail, despite the results actually being correct.
As the result is hard-coded, it makes sense to explicitly use the US locale to
represent those object. I'll open a PR with my solution ASAP.
