Aaron Kimball commented on HDFS-705:
------------------------------------
As a contrasting datapoint, in my own code I often get around this issue by
creating public accessor methods which are named e.g. "getFooForTestingOnly()".
So it's pretty clear that if you're using this, that it's an API not intended
for stable use.
> Create an adapter to access some of package-private methods of DataNode from

> Some of tests from packages other than
> {{org.apache.hadoop.hdfs.server.datanode}} need an access to package-private
> methods of that package. Proposed patch will add new adapter class which will
> have public getter methods to provide such access to outside of the package.
> This is TEST ONLY class: it never has to be used for ANY development purposes.
