The pattern match for finding a start point in the stress test's binary search was based on the explain output, and after memory reservations, was never updated. It had a silent failsafe path and chose the memory limit of impalad as a start point instead. This means the binary search, while known to take a long time, is certainly taking longer than it should.
The current pattern is:
MEM_ESTIMATE_PATTERN = re.compile(r"Estimated.*Memory=(\d+.?\d*)(T|G|M|K)?B")
Tim Armstrong can you confirm we need to match on the second line here?
Max Per-Host Resource Reservation: Memory=156.88MB Per-Host Resource Estimates: Memory=14.67GB
