> For producing the correct filenames for bucketed tables, there is a method in 
> Utilities.java that extracts out the task id from the filename and replaces 
> it with the bucket number. There is a bug in the regex that is used to 
> extract this value for attempt numbers >= 10:
> {code}
> >>> re.match("^.*?([0-9]+)(_[0​-9])?(\\..*)?$", 
> >>> 'attempt_201107090429_6496​5_m_001210_10').group(1)
> '10'
> >>> re.match("^.*?([0-9]+)(_[0​-9])?(\\..*)?$", 
> >>> 'attempt_201107090429_6496​5_m_001210_9').group(1)
> '001210'
> {code}
