Patrick Angeles commented on MAPREDUCE-920:
-------------------------------------------

Could you not support the old params and issue a WARN on the logs for deprecation?

> mapred-default.xml still provides definition for old params which were deprecated in
MAPREDUCE:478. It should be changed to define the new params such as  mapred.map.child.java.opts,
mapred.reduce.child.java.opts, mapred.map.child.env, mapred.reduce.child.env, mapred.map.child.ulimit,
 mapred.reduce.child.ulimit.
