I'm using s3a. I tried to use the vpce dns name but it did not work because the
certificate was expecting bucket. prefix and with the bucket. it fails on
doesBucketExist. so I updated the emr ec2s hosts file with the mapping <vpce
ip> to "s3.us-west-2.amazonaws.com" but it is still calling the endpoint using
the NAT and not using the vpce Ip address.

> URL: https://issues.apache.org/jira/browse/HADOOP-18448
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Environment: Amazon EMR emr-6.5.0 cluster
> Reporter: Einav Hollander
> Priority: Major
>
> I'm using EMR emr-6.5.0 cluster in us-east-1 with ec2 instances. cluster is
> running spark application using pyspark 3.2.1
> EMR is using Hadoop distribution:Amazon 3.2.1
> my spark application is reading from one bucket in us-west-2 and writing to a
> bucket in us-east-1.
> since I'm processing a large amount of data I'm paying a lot of money for the
> network transport . in order to reduce the cost I have create a vpc interface
> to s3 endpoint in us-west-2. inside the spark application I'm using aws cli
> for reading the file names from us-west-2 bucket and it is working through
> the s3 interface endpoint but when I use pyspark to read the data it is using
> the us-east-1 s3 endpoint instead of the us-west-2 endpoint.
> I tried to use per bucket configuration but it is being ignored although I
> added it to the defualt configuration and to spark submit call.
> I tried to set the following configuration but they are ignored:
> '--conf',
> "spark.hadoop.fs.s3a.aws.credentials.provider=com.amazonaws.auth.DefaultAWSCredentialsProviderChain",
> '--conf', "spark.hadoop.fs.s3a.impl=org.apache.hadoop.fs.s3a.S3AFileSystem",
> '--conf', "spark.hadoop.fs.s3a.bucket.<us-west-2-bucket -name>.endpoint=<my
> vpc endpoint>",
> '--conf', "spark.hadoop.fs.s3a.bucket.<us-west-2-bucket
> -name>.endpoint.region=us-west-2",
> '--conf', "spark.hadoop.fs.s3a.bucket.<us-east-1-bucket -name>.endpoint=<vpc
> gateway endpoint>",
> '--conf', "spark.hadoop.fs.s3a.bucket.<us-east-1-bucket
> -name>.endpoint.region=us-east-1",
> '--conf', "spark.hadoop.fs.s3a.path.style.access=false"
