我正在一个具有240GB内存和64个内核的数据块集群中工作。这是我定义的设置。
import pyspark
from pyspark.sql import SparkSession
from pyspark.sql.types import *
import pyspark.sql.functions as fs
from pyspark.sql import SQLContext
from pyspark import SparkContext
from pyspark.sql.functions import count
from pyspark.sql.functions import col, countDistinct
from pyspark import SparkContext
from geospark.utils import GeoSparkKryoRegistrator, KryoSerializer
from geospark.register import upload_jars
from geospark.register import GeoSparkRegistrator
spark.conf.set("spark.sql.shuffle.partitions", 1000)
#Recommended settings for using GeoSpark
spark.conf.set("spark.driver.memory", "20g")
spark.conf.set("spark.network.timeout", "1000s")
spark.conf.set("spark.driver.maxResultSize", "10g")
spark.conf.set("spark.serializer", KryoSerializer.getName)
spark.conf.set("spark.kryo.registrator", GeoSparkKryoRegistrator.getName)
upload_jars()
SparkContext.setSystemProperty("geospark.global.charset","utf8")
spark.conf.set
我正在使用大型数据集，这是我在运行数小时后得到的错误。
