----------------------------------

             Summary: TestDrillbitResilience.doMemoryLeaksWhenCancelled fails with Parquet
async Snappy error
                 Key: DRILL-5157
                 URL: https://issues.apache.org/jira/browse/DRILL-5157
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.9.0
            Reporter: Paul Rogers


Run the {{TestDrillbitResilience.doMemoryLeaksWhenCancelled}} unit test. It fails with the
following stack trace and the memory leak trace shown second.

Stack trace that seems to show that the code was trying to find a Snappy native library:
