Additionally, you can set mapred.local.dir to be a comma-separated
list of paths that reside on multiple disks -- this spreads I/O plus
gives you additional space.

But I suppose if a single Mapper is writing a huge amount of data for
a single partition output, it may cause a disk fill-up. Please correct
me if am wrong here.
