> Set default locale for StopWordsRemover tests to prevent invalid locale error
> during test
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-28365
> URL: https://issues.apache.org/jira/browse/SPARK-28365
> Project: Spark
> Issue Type: Test
> Components: ML, PySpark
> Affects Versions: 3.0.0
> Reporter: Liang-Chi Hsieh
> Priority: Minor
>
> Because the local default locale isn't in available locales at {{Locale}},
> when I did some tests locally with python code, {{StopWordsRemover}} related
> python test hits some errors, like:
> {code}
> Traceback (most recent call last):
> File "/spark-1/python/pyspark/ml/tests/test_feature.py", line 87, in
> test_stopwordsremover
> stopWordRemover = StopWordsRemover(inputCol="input", outputCol="output")
> File "/spark-1/python/pyspark/__init__.py", line 111, in wrapper
> return func(self, **kwargs)
> File "/spark-1/python/pyspark/ml/feature.py", line 2646, in __init__
> self.uid)
> File "/spark-1/python/pyspark/ml/wrapper.py", line 67, in _new_java_obj
> return java_obj(*java_args)
> File /spark-1/python/lib/py4j-0.10.8.1-src.zip/py4j/java_gateway.py", line
> 1554, in __call__
> answer, self._gateway_client, None, self._fqn)
> File "/spark-1/python/pyspark/sql/utils.py", line 93, in deco
> raise converted
> pyspark.sql.utils.IllegalArgumentException: 'StopWordsRemover_4598673ee802
> parameter locale given invalid value en_TW.'
> {code}
> As per [~hyukjin.kwon]'s advice, instead of setting up locale to pass test,
> it is better to have a workable locale if system default locale can't be
> found in available locales in JVM. Otherwise, users have to manually change
> system locale or accessing a private property _jvm in PySpark.
