Pyspark S3 错误：java.lang.NoClassDefFoundError：com/amazonaws/services/s3/model/MultiObjectDeleteException

Question

Been unsuccessful setting a spark cluster that can read AWS s3 files. The software I used are as follows:

1. hadoop-aws-3.2.0.jar
2. aws-java-sdk-1.11.887.jar
3. spark-3.0.1-bin-hadoop3.2.tgz

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))

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

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.

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.

Answer 1

Hadoop 3.2 was built against 1.11.563; stick the full shaded sdk of that specific version in your classpath "aws-java-sdk-bundle" and all should be well.

The SDK has been "fussy" in the past...and upgrade invariably causes surprises. For the curious Qualifying an AWS SDK update . It's probably about time someone does it again.

Answer 2

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

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 )

Answer 3

So I cleaned-up everything and re-installed the following versions of jars and it worked: hadoop-aws-2.7.4.jar, aws-java-sdk-1.7.4.2.jar. Spark install version: spark-2.4.7-bin-hadoop2.7. Python version: Python 3.6.

Answer 4

In addition to the answers, I will add my 2 cents on top of them. Although adding the aws-java-sdk-bundle works perfectly, I found it better to add the specific dependencies to make the package smaller.

I replaced aws-java-sdk-bundle by aws-java-sdk-sts , aws-java-sdk-s3 , and aws-java-sdk-dynamodb . The final size went from ~200MB to ~125MB.
