I'm trying to better understand the meaning of the annotations defined in org.apache.hadoop.classification.InterfaceAudience. 1. Private is documented as being "Intended for use only within Hadoop itself". Does this mean the whole Hadoop project, or the subproject that the annotated element is in? (Or another scope?)
Private means private to the subproject (ie private to HDFS, to MR, etc).
We should update the doc to clarify this.
2. Is a contrib module considered to be a part of the subproject? For example, if something is marked as LimitedPrivate in Common say, with intended audience MapReduce, can MapReduce contrib modules use it?
I believe the answer should be no.
Or, assuming the second meaning for 1, if something is marked as Private in MapReduce, can MapReduce contrib modules use it?
Again I believe the answer should be no. Any concrete examples that we can use to examine/discuss this further
Thanks, Tom
