Description

Run the unit test CsvTest from the master branch in the Eclipse debugger. The test will emit the following to the console:

17:54:58.347 [238e068f-7d4e-838b-7e9e-b6958f977f65:frag:0:0] ERROR o.a.d.e.physical.impl.BaseRootExec - Batch dump started: dumping last 2 failed batches

The tests all pass. It is not clear why we get the above error. However, it is something that should be investigated and fixed since it causes "noise" when trying to get a clean test run.
