If I use the following parameters in mapred.child.java.opts, then the Reduce tasks will inmediately fail with exit code 1.
-Dcom.sun.management.jmxremote.port=7575 - Dcom.sun.management.jmxremote.authenticate=false - Dcom.sun.management.jmxremote.ssl=false The problem is the fact that there are 2 JVM's spawned with this parameters, despite the fact that tasks/node is 1. (The Reduce task is already being started sort of, along with the Map task). So how do I enable remote jmx connecting?
