Subject [jira] Commented: (HDFS-705) Create an adapter to access some of package-private methods of DataNode from tests
Date Wed, 14 Oct 2009 23:26:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765811#action_12765811
] 

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.

> 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.
