Description

I created 1 2 shard X 2 replica collection . Here's the log entry for it

2017-11-27 06:43:47.071 INFO  (qtp159259014-22) [   ] o.a.s.h.a.CollectionsHandler Invoked Collection Action :create with params replicationFactor=2&routerName=compositeId&collection.configName=_default&maxShardsPerNode=2&name=test_recovery&router.name=compositeId&action=CREATE&numShards=2&wt=json&_=1511764995711 and sendToOCPQueue=true

And then when I look at the state.json file I see nrtReplicas is set to 1. Any combination of numShards and replicationFactor without explicitly specifying the "nrtReplicas" param puts the "nrtReplicas" as 1 instead of using the replicationFactor value

{"test_recovery":{
    "pullReplicas":"0",
    "replicationFactor":"2",
...
    "nrtReplicas":"1",
    "tlogReplicas":"0",
..
