["Uwe L. Korn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16239011#comment-16239011 ] 

Uwe L. Korn commented on ARROW-1762:
------------------------------------

See the SO answer to this problem: https://stackoverflow.com/a/19905162/1689261 This is probably due to missing locales on the system. I'm not sure if we can do anything here, this might be a requirement of the external functions we're calling.
