Subject Re: only one map or reduce job per time on one node
Date Tue, 05 Nov 2013 19:29:43 GMT
Because my node swaps the memory if the 2 map slots + 1 reduce is occupied
with my job. Sure I can minimize the max memory for the map/reduce process.
I tried this already, but I got a out of memory exception if set the max
heap size for the map/reduce process to low for my mr job.

kind regards
