I am working with the mongo hadoop connector on a replica set and I want to use it on a secondary machine. The mongo hadoop driver runs `splitVector` (https://github.com/mongodb/mongo-hadoop/blob/master/core/src/main/java/com/mongodb/hadoop/splitter/StandaloneMongoSplitter.java#L94). However, splitVector can't be run against a secondary machine:
Can someone explain the reason for this? It would be great if we could use the mongo hadoop connector on a non-primary machine and this appears to be a blocking issue for that to happen.
