>                 Key: DRILL-5157
>                 URL: https://issues.apache.org/jira/browse/DRILL-5157
>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.9.0

> Run the {{TestDrillbitResilience.doMemoryLeaksWhenCancelled}} unit test. It fails with
the following stack trace and the memory leak trace shown second.
> Strangely, this error appears only if the test is run as part of the overall suite. The
error does not appear if the test is run individually in the debugger. This suggests that
the problem described here is a side-effect of a problem created by an earlier test.
> Stack trace that seems to show that the code was trying to find a Snappy native library:
