Error when using Pig 0.8.1 in local mode from Java
Hi,
I'm trying to run PIG 0.8.1 in loval mode from Java.
My code used to work with PIG 0.6.1.
Now, I got the following exception:
java.io.FileNotFoundException: File
file:/tmp/hadoop-vbarat/mapred/system/job_local_0001/job.xml does
not exist.

Any idea ?
Thanks a lot
Re: Error when using Pig 0.8.1 in local mode from Java
Posted by Vincent Barat <vb...@ubikod.com>.
Actually, hadoop creates 2 directories in my /tmp (I use hadoop
default configuration (empty conf files) when in local mode):
hadoop-${user.name}
hadoop-vbarat
I guess that there is a bug in hadoop (at least when using MacOS X) :
${user.name} is not replaced by my user name (vbarat) in some case.
As a work arround, I created a symbolic link:
lrwxr-xr-x 1 vbarat wheel 13 27 jui 12:20
hadoop-${user.name}@ -> hadoop-vbarat
drwxr-xr-x 4 vbarat wheel 136 27 jui 12:20 hadoop-vbarat/
and it works.
