This can make the test fail intermittently. Maybe add a small delay (Thread.sleep(500)) after client.close() to handle that? ########## hadoop-tools/hadoop-azure/src/test/java/org/apache/hadoop/fs/azurebfs/services/TestAbfsClient.java: ########## @@ -0,0 +1,118 @@ +/** + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
