> The embedded JVM by default uses 1/4 of system memory, which means potentially up to 3/4 of system memory on a 3 node minicluster. IMPALA-6070 addresses this for the docker case, but in general it would be good to solve this for all miniclusters and ensure that all tests work with a smaller heap size so that memory is not overcommitted in our test environments.
> I tried running end-to-end tests with a 1Gb heap and ran into out-of-memory for test_insert_large_string.
