我試圖創建jsonrdd使用SQL上下文,但得到下面的錯誤。我已經把代碼和下面的錯誤..請建議..星火SQL JSON錯誤
我的代碼:
rdd1=sqlContext.jsonRDD('/idn/home/ijamalmo/ibfiles/datafiles/sampledata.json')
錯誤
Traceback (most recent call last):
File "", line 1, in
File "/opt/mapr/spark/spark-1.4.1/python/pyspark/sql/context.py", line 442, in jsonRDD
keyed = rdd.mapPartitions(func)
AttributeError: 'str' object has no attribute 'mapPartitions'
sqlCon = SQLContext(SC) RDD1集= sqlCon.jsonFile( 'smapledata.json') 該命令沒有任何錯誤執行。但是,當我試圖打印架構或打印數據它thrwoing錯誤 rdd1.printSchema() rdd1.collect() 請指教 –
