Hemanth Yamijala commented on MAPREDUCE-979:
--------------------------------------------

+1 for the 20 patch, other than the correction in the javadoc similar to what's been applied
for trunk. Please upload a corresponding 20 patch once the trunk patch passes Hudson.

has the default value of -1.
