Subject How mapred.map.child.java.opts influence the Container resource allocation
Date Mon, 04 Feb 2013 11:38:37 GMT
Hi All

    I use YARN and MR.I am confused by the relationship between
mapred.map.child.java.opts and  Container resource  allocation.
    if I setup mapred.map.child.java.opts = -Xmx2048m ,on nodemanager
how Containers will be allocated according to this settings.
     what about mapred.reduce.child.java.opts?
