Change subject: IMPALA-6917: Limit impalad mem-limit to 12GB. ...................................................................... IMPALA-6917: Limit impalad mem-limit to 12GB. This changes the memlimit choosing code in start-impala-cluster to have a maximum of 12GB. In 68GB machines, this has the effect of reducing the memlimit from ~15.8GB to 12GB. On machines with less than 51.4 GB of RAM, this has no effect. I'm tinkering with this threshold because ASAN builds sometimes die at the hands of the OOM killer on m2.4xlarge machines (68GB). My theory for why it's only sometimes is that during the parallel tests, our memory usage could vary widely depending on which tests and queries execute. End-users don't see this code; this is only used by our minicluster tests to test Impala. I have run the ASAN build with this change successfully, though I've found this particular OOM seems to come and go.
