我在spark-2.1.0-bin-hadoop2.7，Scala 2.11.8 & python3.5。pyspark mongoDB連接器問題
對於火花蒙戈連接器我正在佈置一個罐子中../spark-2.1.0-bin-後使用「蒙戈-火花connector_2.11-2.0.0.jar」從http://repo1.maven.org/maven2/org/mongodb/spark/mongo-spark-connector_2.11/2.0.0/
現在hadoop2.7 /罐路徑，我開始我的./pyspark如下官方蒙戈商務部網站https://docs.mongodb.com/spark-connector/master/python-api/#tutorials
./bin/pyspark --conf "spark.mongodb.input.uri=mongodb://127.0.0.1/test.myCollection?readPreference=primaryPreferred"
--conf "spark.mongodb.output.uri=mongodb://127.0.0.1/test.myCollection" \
--packages org.mongodb.spark:mongo-spark-connector_2.11:2.0.0
一切都很好，我得到我的sparksession對象火花。
現在，當我試圖收集加載到數據幀
df = spark.read.format("com.mongodb.spark.sql.DefaultSource").option("uri","mongodb://127.0.0.1/test.myCollection").load()
我getitng此錯誤：

我只是想不通：我在做什麼錯了，我很想念
待辦事宜我添加任何依賴的jar
-or這個連接到構造函數僅用於2.0.x版本，而不是spark2.1.0（絕對不要嘗試在spark2.0.x）
- 什麼，如果有對MongoDB的一個授權，那麼如何將我的URI看起來像
- 因爲它顯示connectionString，但我已經重新檢查100次（同樣在pymongo連接url）。
- 也試圖與會話生成器對象，但沒有結果
from pyspark.sql import SparkSession
my_spark = SparkSession \
.builder \
.appName("myApp") \
.config("spark.mongodb.input.uri", "mongodb://127.0.0.1/test.coll") \
.config("spark.mongodb.output.uri", "mongodb://127.0.0.1/test.coll") \
.getOrCreate()
請幫我整理了這一點是相同的。提前致謝。
