I thought about it, but: # It's a (potential) internal detail of the node label implementation, with other classes in the package # The {{nodelabels}} package is sparse right now # None of these classes are user-facing, so they're easy to move So I put in in the {{nodelabels}} package, but don't have a strong opinion. was (Author: chris.douglas): bq. do you think is it better to place this module to org.apache.hadoop.yarn.server.resourcemanager.nodelabels.matcher (or evaluator) for better organization?
