Andrew Ash commented on SPARK-18359:
I agree with Sean -- using the submitting JVM's locale is insufficient. Some
users will want to join CSVs with different locales, and that doesn't offer a
means of using different locales on different files. This really should be
specified on a per-csv basis, which is why I think the direction [~abicz]
suggested supports this nicely:
{noformat}
spark.read.option("locale", "value").csv("filefromeurope.csv")
{noformat}
where the value is something we can use to get a {{java.util.Locale}}
Has anyone worked around this functionality gap in a useful way, or do we still
need to work through these Locale issues in spark-csv?

Input would mysteriously work on one machine and not another, or succeed but quietly give the wrong output. It also caused some SQL-related methods to return the wrong value on non-US-locale machines. That's a big(ger) problem that had to be fixed. Yes, the problem is there isn't a way to specify non-US locales just for the CSV parsing. That's what this is about, and yes you should work on it if you need the functionality. As a workaround you can do some preprocessing to parse the dates manually. Not great, but not hard either. > Let user specify locale in CSV parsing > -- > > Key: SPARK-18359 > URL: https://issues.apache.org/jira/browse/SPARK-18359 > Project: Spark > Issue Type: Improvement > Components: SQL >Affects Versions: 2.0.0, 2.0.1 >Reporter: yannick Radji > > On the DataFrameReader object there no CSV-specific option to set decimal > delimiter on comma whereas dot like it use to be in France and Europe. -- This message was sent by Atlassian JIRA (v6.3.15#6346) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

When we submit a Job to our cluster we have to tell Spark that it requires DE locale as our data are coming in the corresponding format. After the migration from 1.6 to 2.1 we had to give up usage of any type apart of string for parsing of CSV data (sounds not like it's a correct way to me). I can not see why exactly the changes required for SPARK-18076 have been made. But at the moment there is no possibility to parse CSV data formatted using locale different from US and this appears to me like a quite big restriction. > Let user specify locale in CSV parsing > -- > > Key: SPARK-18359 > URL: https://issues.apache.org/jira/browse/SPARK-18359 > Project: Spark > Issue Type: Improvement > Components: SQL >Affects Versions: 2.0.0, 2.0.1 >Reporter: yannick Radji > > On the DataFrameReader object there no CSV-specific option to set decimal > delimiter on comma whereas dot like it use to be in France and Europe. -- This message was sent by Atlassian JIRA (v6.3.15#6346) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

Can interface to specify locale looks like?:
spark.read.option("numberLocale", "German").csv("filefromeurope.csv")
