MapR appears to make the general assumption that MapR nodes won't run any major non-MapR services. This is specifically related to it using 'allish' memory not associated to one of it services when allocating map and reduce task memory. If I have a fairly heavy (memory-wise) service running on some nodes, can I tell MapR to do it's standard warden calculations but consider a set megabytes of memory offlimits? For example, if I have 32gb of memory but one of my non-MapR services utilizes 8gb of memory, is there a way to tell MapR to operate as if there were only 24gb? Or at this point, do I have manage all the memory settings manually?
