I am struggling with writing Iterator tests for ACCUMULO-1280. One Iterator in particular makes me scratch my head is the OrIterator. It doesn't have a Test (ACCUMULO-3208) and some of the code appears stale/illogical. This class, combined with my other Iterator struggles, makes me wonder if there are some classes than can be deprecated...
./apache/accumulo/core/iterators$ ls *.java system/*.java user/*.java | wc -l 72 Just looking at numbers between these 3 directories we have 72 classes pertaining to Iterators/Filters/Combiners. Can any of these safely be deprecated in 2.0.0? We already have this ticket <https://issues.apache.org/jira/browse/ACCUMULO-3521> for unused Iterator classes. Instead of creating tests for these classes, could they be deprecated?
