             Summary: test_scanners_fuzz.py::TestScannersFuzzing failing on exhaustive release build
                 Key: IMPALA-5820
                 URL: https://issues.apache.org/jira/browse/IMPALA-5820
             Project: IMPALA
          Issue Type: Bug
            Reporter: David Knupp
            Priority: Critical


I'm seeing multiple tests failing fromthe {{TestScannersFuzzing}} suite when running exhaustive tests on the release build. There are no crashes or backtraces, but that test suite was last touched as part of the patch for IMPALA-5776, and there appear to be HdfsScanNode-related errors in log files that correspond with the time of the test failures, e.g.

This makes me wonder if these might also be related to IMPALA-5819.

Taras, who submitted the patch for IMPALA-5776 is away, so assigning to [~alex.behm] who reviewed the patches for both IMPALA-5776 and IMPALA-5819. Please reassign as you see fit.
