Как исправить ошибку java.lang.OutOfMemoryError при попытке сохранить файл паркета в S3 - PullRequest

/ 30 апреля 2019

Я пытаюсь использовать AWS Glue для ETL.Я вижу последний кадр.При попытке сохранить его на S3 в качестве паркета.Я получал

ExecutorLostFailure (executor 29 exited caused by one of the running tasks) Reason: Container killed by YARN for exceeding memory limits. 5.9 GB of 5.5 GB physical memory used. Consider boosting spark.yarn.executor.memoryOverhead

Поэтому я решил разделить операцию write_dynamic_frame с помощью.

glueContext.write_dynamic_frame.from_options(frame = dynamic_finalframe, connection_type = "s3", connection_options = {"path": s3_path, "partitionKeys":["customer_country"]}, format = "parquet")

Примечание. Я уже пометил неиспользуемый фрейм данных для сбора мусора, используя df.unpersist()

Теперь я не получаю

Container killed by YARN for exceeding memory limits

Теперь я получаю

Caused by: org.apache.spark.SparkException: Job aborted due to stage failure: Task 118 in stage 56.0 failed 4 times, most recent failure: Lost task 118.3 in stage 56.0 (TID 4104, ip-172-32-105-33.ec2.internal, executor 39): java.lang.OutOfMemoryError: Unable to acquire 262144 bytes of memory, got 65536

Вот полная ошибка

An error occurred while calling o2076.pyWriteDynamicFrame.

Согласно этому документу AWS https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-etl-glue-arguments.html Amazonупоминание не использовать –conf
