> HDFS-6693 introduced some debug message to debug why when
> TestPipelinesFailover fails.
> HDFS-9438 restricted the debug message to Linux/Mac/Solaris. However, the
> test would fail when printing debug message if "ifconfig" command is not
> available in certain environment.
> This is not quite right. The test should not fail due to the debug message
> printing. We should catch any exception thrown from the code that prints
> debug message, and issue a warning message.
> Suggest to make this change.
