Hi, on our cluster our jobs usually satisfied with less than 2 GB of heap space. so we have on our 8 GB computers 3 maps maximum and on our 16 GB computers 4 maps maximum (we only have quad core CPUs and to have memory left for reducers). This works very well.
But now we have a new kind of jobs. Each mapper requires at lest 4 GB of heap space. Is it possible to limit the number of tasks (mapper) per computer to 1 or 2 for these kinds of jobs ? Regards, Marco
