The version of Mongo Db is 3.4 and the following is the code snippet.
MongoClient client = new MongoClient("localhost", 27017);
#SuppressWarnings("deprecation")
DB db = client.getDB("db");
DocumentNodeStore ns = new DocumentMK.Builder().
setMongoDB(db).getNodeStore();
So when i am trying create the DocumentNodeStore, i am getting the following exception.
Exception in thread "main" com.mongodb.MongoCommandException: Command failed with error 197: 'The field 'unique' is not valid for an _id index specification. Specification: { v: 2, key: { _id: 1 }, name: "_id_1", ns: "db.blobs", unique: true }' on server localhost:27017. The full response is { "ok" : 0.0, "errmsg" : "The field 'unique' is not valid for an _id index specification.

So far my understanding was to downgrade the MongoDb to avoid the exception. But i have to use the latest version considering the other dependencies. please correct me if i am wrong and suggest me the steps that i need to look.
