That's odd. Please double check you are running debug builds. Alternately, you can try:
impala-py.test tests/custom_cluster/test_alloc_fail.py Another approach is to try doing what the test is trying to achieve manually: ./bin/start-impala-cluster.py --impalad_args="--stress_fn_ctx_alloc=1" ./bin/impala-shell.sh -q "select rand() from functional.alltypes" My suspicion is that your change modified some states used for rand() and it bloated from 4 bytes to 5000 bytes. The error string needs to be updated as a result. That said, did anyone ask about the change in memory usage during code review ?
