Pyspark S3错误:java.lang.NoClassDefFoundError:com/amazonaws/services/s3/model/MultiObjectDeleteException [英] Pyspark S3 error: java.lang.NoClassDefFoundError: com/amazonaws/services/s3/model/MultiObjectDeleteException
问题描述
由于未成功设置可以读取AWS s3文件的Spark集群.我使用的软件如下:
Been unsuccessful setting a spark cluster that can read AWS s3 files. The software I used are as follows:
- hadoop-aws-3.2.0.jar
- aws-java-sdk-1.11.887.jar
- spark-3.0.1-bin-hadoop3.2.tgz
使用python版本:Python 3.8.6
Using python version: Python 3.8.6
from pyspark.sql import SparkSession, SQLContext
from pyspark.sql.types import *
from pyspark.sql.functions import *
import sys
spark = (SparkSession.builder
.appName("AuthorsAges")
.appName('SparkCassandraApp')
.getOrCreate())
spark._jsc.hadoopConfiguration().set("fs.s3a.access.key", "access-key")
spark._jsc.hadoopConfiguration().set("fs.s3a.secret.key", "secret-key")
spark._jsc.hadoopConfiguration().set("fs.s3a.impl","org.apache.hadoop.fs.s3a.S3AFileSystem")
spark._jsc.hadoopConfiguration().set("com.amazonaws.services.s3.enableV4", "true")
spark._jsc.hadoopConfiguration().set("fs.s3a.aws.credentials.provider","org.apache.hadoop.fs.s3a.BasicAWSCredentialsProvider")
spark._jsc.hadoopConfiguration().set("fs.s3a.endpoint", "")
input_file='s3a://spark-test-data/Fire_Department_Calls_for_Service.csv'
file_schema = StructType([StructField("Call_Number",StringType(),True),
StructField("Unit_ID",StringType(),True),
StructField("Incident_Number",StringType(),True),
...
...
# Read file into a Spark DataFrame
input_df = (spark.read.format("csv") \
.option("header", "true") \
.schema(file_schema) \
.load(input_file))
代码开始执行spark.read.format时失败.看来找不到课程.java.lang.NoClassDefFoundError:com.amazonaws.services.s3.model.MultiObjectDeleteException
The code fails when it starts to execute the spark.read.format. It appears that it can't find the class. java.lang.NoClassDefFoundError: com.amazonaws.services.s3.model.MultiObjectDeleteException

我一直在尝试为上述jar和python找到合适的组合，但找不到合适的组合.我遇到了各种各样的NoClassDefFoundError，所以我决定使用上面列出的所有jar和python的最新版本，但仍未成功.
I've been trying to find the right combination for the above jars and python but I couldn't find the right mix. I'm getting all kinds of NoClassDefFoundError so I decided to use the latest versions of all the jars and python I listed above but still unsuccessful.
我想知道您使用哪个版本的jar和python成功建立了一个能够通过pyspark使用s3a访问s3的集群?预先感谢您的回复/帮助.
I would like to know what versions of jars and python did you use to have successfully setup a cluster that is able to access s3 using s3a via pyspark? Thank you in advance for response/help.
推荐答案
我能够在Spark 3.0/Hadoop 3.2上解决此问题.我也在这里记录了我的答案-
I was able to solve this issue on Spark 3.0/ Hadoop 3.2. I documented my answer here as well - AWS EKS Spark 3.0, Hadoop 3.2 Error - NoClassDefFoundError: com/amazonaws/services/s3/model/MultiObjectDeleteException
使用以下AWS Java SDK捆绑包，此问题将得到解决-
Use following AWS Java SDK bundle and this issue will be solved -
aws-java-sdk-bundle-1.11.874.jar( https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-bundle/1.11.874 )
aws-java-sdk-bundle-1.11.874.jar (https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-bundle/1.11.874)
