The test TestNativeAzureFileSystemClientLogging is failing; with some extra diagnostics it implies that the log isn't being captured.
This test is primarily about verifying that things get logged, grabbing the log and then looking for the presence/absence of log output.
This makes it brittle to: changes in log output, log messages, and here: log wiring.
Do we need to retain this test at all? If yes,then log capture needs to be looked again (
HADOOP-13470 covers its past). If no: delete and let's not worry about it.
