possible resource leak in capacity scheduler
Radim Kolar 2012-10-15, 09:44
i have simple 2 node cluster. one node with 2 GB and second with 1 GB RAM

on node with 1 GB is running application master - no memory left,
nothing runs on node with 2 GB RAM

current application do not runs, it has only AM started and no resources
for running mapper. If you take a look at screenshot from scheduler,
interesting is that memory total is cluster metrics is just 1 GB.
