Python 3.x 在Windows 10上实例化pyspark sparksession会产生一系列与配置单元会话相关的问题
我不确定发生了什么，但在windows上实例化sparksession时遇到了问题。 我能够毫无问题地实例化sparkcontext并执行RDD，如下所示：Python 3.x 在Windows 10上实例化pyspark sparksession会产生一系列与配置单元会话相关的问题,python-3.x,pyspark,windows-10,apache-spark-sql,anaconda,Python 3.x,Pyspark,Windows 10,Apache Spark Sql,Anaconda,我不确定发生了什么，但在windows上实例化sparksession时遇到了问题。 我能够毫无问题地实例化sparkcontext并执行RDD，如下所示： sc= SparkContext.getOrCreate() import numpy as np rdd=sc.parallelize(range(100)) rdd.map(lambda x: x+1).take(10) 该文件的输出整洁地打印如下：- [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] 但是，当我尝试使
sc= SparkContext.getOrCreate()
import numpy as np
rdd=sc.parallelize(range(100))
rdd.map(lambda x: x+1).take(10)
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sp= SparkSession.builder.master("local").appName("multiclassifier").getOrCreate()
#sc= SparkContext.getOrCreate()
#sp = SQLContext.getOrCreate(sc).sparkSession
#sp= SparkSession.builder.master("local").enableHiveSupport().getOrCreate()
sc=sp.sparkContext
#sc= SparkContext.getOrCreate()
XY=np.concatenate((y,X),axis=1)
print(XY[0:2])
pXYdf=pd.DataFrame(XY)
sXYdf=sp.createDataFrame(pXYdf)
print(sXYdf.head())

import pyspark
import pyspark.sql as sq # to get your spark session.
# Now instantiate your spark session using builder..
