Description

The exhaustive test failed with the following. We have seen this failure once more before in May. It looks like it is lzo-related.

REGRESSION:  query_test.test_queries.TestQueries.test_file_partitions[exec_option: {'disable_codegen': True, 'abort_on_error': 1, 'exec_single_node_rows_threshold': 0, 'batch_size': 0, 'num_nodes': 0} | table_format: text/lzo/block]

Error Message:
test failure
