-------------------------------------------------

It applies to 0.17, if you replace src/mapred with src/java in the patch.

> When dfs is getting full (80+% of reserved space), the rate of write failures increases,
such that more map-reduce tasks can fail. By not cleaning up the temporary output directory
of tasks the situation worsens over the lifetime of a job, increasing the probability of the
whole job failing.
