----------------------------------------
are you sure that you started the job with -x local?
> Intermediate data lost in local mode
> ------------------------------------
>
> Key: PIG-1767
> URL: https://issues.apache.org/jira/browse/PIG-1767
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.7.0, 0.8.0
> Environment: Windows 7/64bit running in Cygwin
> Reporter: John Meagher
>
> When running the script below it fails because one of the intermediate data
> files is not available one of the follow-on steps. This fails under both
> 0.7.0 and the 0.8.0-rc. This works fine on 0.7.0 when run against HDFS.
