Impala 2.8.0
Description
Nightly exhaustive builds are failing. From the Jenkis console:
ERROR query_test/test_scanners_fuzz.py::TestScannersFuzzing::()::test_fuzz_alltypes[exec_option: {'disable_codegen': False, 'abort_on_error': 1, 'exec_single_node_rows_threshold': 0, 'batch_size': 0, 'num_nodes': 0} | table_format: text/lzo/block]
It looks like this has something to do with the lzo scanner.
From impalad.FATAL:
F1018 15:45:14.758010 7262 hdfs-lzo-text-scanner.cc:236] Check failed: read_until > unprocessed_bytes (0 vs. ^A) F1018 15:45:14.781767 7254 hdfs-lzo-text-scanner.cc:236] Check failed: read_until > unprocessed_bytes (0 vs. ^E)
Another strange thing is that 3 minidumps get produced and saved in our logs (1 for every Impalad), but a core dump does not get generated. A core dump should be generated if a DCHECK is hit.
tarmstrong, I think you've dealt with issues uncovered by fuzz testing before, so I'll assign this to you.
