Write Concern used in Mongo-Hadoop Connector

[Deepesh Maheshwari]

Hi,
I am using below code to insert data in mongodb from spark.

JavaPairRDD<Object, BSONObject> rdd;

Configuration config = new Configuration();

config.set("mongo.output.uri", SparkProperties.MONGO_OUTPUT_URI);
        config.set("mongo.output.format",
"com.mongodb.hadoop.MongoOutputFormat");

rdd.saveAsNewAPIHadoopFile("file:///notapplicable",
                            Object.class, BSONObject.class,
MongoOutputFormat.class, config);

But, looking in the code i am not able to figure out what write concern
api's are using to insert  data in mongodb.

Please explain and let me know if someone figure out.

Thanks,
Deepesh
