Hi
If your intension is controlling the number of attempts every task make, then
the property to be tweaked is
mapred.map.max.attempts
The default value is 4, for no map task re attempts make it 1.

not useful.
Besides Speculative execution , Tasks can be attempted multiple times due
to failures.
So you can see 3 attempt there.
