我确实在jupyter中创建了笔记本
SPARK_MAJOR_VERSION=2 PYSPARK_DRIVER_PYTHON=jupyter PYSPARK_DRIVER_PYTHON_OPTS='notebook --ip=hadoop-edge-001 --no-browser --port=8888' pyspark --master yarn-client --driver-memory 25g --executor-memory 50g --num-executors 100 --conf "spark.executor.cores=10" --conf "spark.ui.port=8072" --conf "spark.driver.maxResultSize=0" --conf "spark.serializer=org.apache.spark.serializer.KryoSerializer" --conf "spark.kryoserializer.buffer.max=1024m" --conf "spark.shuffle.service.enabled=true" --conf "spark.dynamicAllocation.enabled=true" --conf "spark.dynamicAllocation.minExecutors=2" --conf "spark.dynamicAllocation.initialExecutors=100"
在笔记本中执行后：
import pyspark
sc = pyspark.SparkContext(aplicationName="aerobus")
返回错误：
