Subject [jira] [Commented] (HIVE-1402) Add parallel ORDER BY to Hive
Date Sun, 23 Jun 2013 12:24:21 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13691446#comment-13691446
] 

Navis commented on HIVE-1402:
-----------------------------

I've seen code in FileInputFormat in hadoop which ignores files starting with '_' and '.'
 
{noformat}
private static final PathFilter hiddenFileFilter = new PathFilter(){
  public boolean accept(Path p){
    String name = p.getName(); 
    return !name.startsWith("_") && !name.startsWith("."); 
  }
}; 
{noformat}

If it's convention as you said, I don't bother changing it to '_' (I'll update it tomorrow
morning). Thanks for review!
