> The /tmp/temp* directory is generated using Random.nextInt(). The collision of the random integers generated may occur. This issue was seen quite a few times.

> A workaround is to change the base directory(for some group) *pig.temp.dir* to avoid this rare conflict.
> for example:
> {noformat}
> pig -Dpig.temp.dir=/tmp/$USER/$RANDOM pig_script.pig
> {noformat}
