hi, 
how can i know where i need to put the following conf parameters? 
do i need the mapred-site.xml to be the same on all nodes? 

    io.sort.mb
    io.sort.factor
    io.sort.spill.percent
    tasktracker.http.threads

i can see it on MapR documentation under Job conf, does it mean i have to add it only on JT conf file? 
if i see under Task configuration, it mean i need to add it on all the tasktrackers?

Thanks.
