velox/common/caching/tests/AsyncDataCacheTest.ssd is flaky

[pedroerp]

Just caught the error in circleCI running on main branch:

https://app.circleci.com/pipelines/github/facebookincubator/velox/10898/workflows/7c8a19a8-7fee-4fdb-9631-aa7bc7627091/jobs/63441

The test is flaky, but you can usually reproduce it by running it 10+ times. The failed assert is:

4: ../../velox/common/caching/tests/AsyncDataCacheTest.cpp:645: Failure
4: Expected equality of these values:
4:   0
4:   stats2.numPins
4:     Which is: 8
4: ../../velox/common/caching/tests/AsyncDataCacheTest.cpp:648: Failure
4: Expected equality of these values:
4:   0
4:   ramStats.numExclusive
4:     Which is: 8

and the test prints a bunch of these error messages right before:

E0727 15:32:43.455669 2134341 Exceptions.h:68] Line: velox/common/caching/tests/AsyncDataCacheTest.cpp:328, Function:loadOne, Expression: !injectErrorTesting error, Source: RUNTIME, ErrorCode: INVALID_STATE

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.

Closing this as it is the same as a recently filed issue.
