We've observed empirically that giving Impala 80% of system memory doesn't leave enough room for the minicluster and ASAN overhead, leading to the OOM killer striking during test runs (sometimes). This commit reduces the threshold to 70%. This commit also reduces the memory usage of semi-joins-exhaustive.test by roughly halving the number of records it deals with. This was necessary for tests to pass on a machine with 32GB of RAM. Testing: I've run the ASAN build (more) happily with this change. I've run exhaustive tests on a 32GB machine.
