             Summary: TestDateFunctions#testToChar fails when the locale is non-English
                 Key: DRILL-4225
                 URL: https://issues.apache.org/jira/browse/DRILL-4225
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Data Types
    Affects Versions: 1.4.0
         Environment: Mac OS X 10.10.5
            Reporter: Akihiko Kusanagi


Set the locale to ja_JP on Mac OS X: 
{noformat}
$ defaults read -g AppleLocale

{noformat}

TestDateFunctions#testToChar fails with the following output:
{noformat}

Test queries are like this:
{noformat}
to_char((cast('2008-2-23' as date)), 'yyyy-MMM-dd')
to_char(cast('12:20:30' as time), 'HH mm ss')
to_char(cast('2008-2-23 12:00:00' as timestamp), 'yyyy MMM dd HH:mm:ss')
{noformat}
This failure occurs because org.joda.time.format.DateTimeFormat interprets the pattern 'MMM' differently depending on the locale. This will probably occur in other OS platforms.
