| # Regression test for IMPALA-2256. Join whose right side has very high |
| # cardinality (60M) and zero materialized slots. |
| # Because the right side of the join here is always |
| # the same key, this query can run out of memory and fail to spill; see |
| # IMPALA-4857. The cardinality (60M) is chosen so that the test |
| # runs when impalad has a 7.8GB memlimit. (The peak memory usage |
| # of the relevant fragment is 3.6GB when tested.) |
