I am trying to write data on an S3 bucket from my local computer:
spark = SparkSession.builder \
.appName('application') \
.config("spark.hadoop.fs.s3a.access.key", configuration.AWS_ACCESS_KEY_ID) \
.config("spark.hadoop.fs.s3a.secret.key", configuration.AWS_ACCESS_SECRET_KEY) \
.config("spark.hadoop.fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem") \
.getOrCreate()
lines = spark.readStream \
.format('kafka') \
.option('kafka.bootstrap.servers', kafka_server) \
.option('subscribe', kafka_topic) \
.option("startingOffsets", "earliest") \
.load()
streaming_query = lines.writeStream \
.format('parquet') \
.outputMode('append') \
.option('path', configuration.S3_PATH) \
.start()
streaming_query.awaitTermination()
Hadoop version: 3.2.1, Spark version 3.2.1
I have added the dependency jars to pyspark jars:
spark-sql-kafka-0-10_2.12:3.2.1, aws-java-sdk-s3:1.11.375, hadoop-aws:3.2.1,
I get the following error when executing:
py4j.protocol.Py4JJavaError: An error occurred while calling o68.start.
: java.io.IOException: From option fs.s3a.aws.credentials.provider
java.lang.ClassNotFoundException: Class
