[jira] [Commented] (PIG-1767) Intermediate data lost in local mode
[ https://issues.apache.org/jira/browse/PIG-1767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238023#comment-13238023 ]
Zach Garner commented on PIG-1767:
----------------------------------
I have the same problem. Order works using "-x local" but not via "-x mapreduce".
I'm running on Ubuntu, using the system packages for hadoop & pig.
zach@ubuntu:~$ uname -a
Linux ubuntu 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux
zach@ubuntu:~$ dpkg -l|grep pig
ii pig 0.9.2
zach@ubuntu:~$ dpkg -l|grep hadoop
ii hadoop 1.0.1

> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.7.0, 0.8.0
> Environment: Windows 7/64bit running in Cygwin with Pig in MR mode and Hadoop using the local file system
> 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.
