> Pasting comments of Pi Song. 
> "I think the concept of multi-dir temp file creator (LocalDirAllocator in Hadoop) should be adopted to Pig. What it does is:-
>     * You can set up a set of tmp file dirs in configuration (They can be on different physical drives so you can utilize more disk space)
>     * When a temp file is being created, the system will probe the given temp dirs in round-robin fashion
>     * For a selected temp dir, if it exists and you have permission to write, temp file will be created
>     * For a selected temp dir, it it doesn't exist or you don't have permission to write, the temp dir will be kept in the black list, thus not being used later on.
>     * For the next temp file, move on to the next temp dir
