             Summary: AWS SDK V2 - Update S3A region logic 
                 Key: HADOOP-19044
                 URL: https://issues.apache.org/jira/browse/HADOOP-19044
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.4.0
            Reporter: Ahmar Suhail


If both fs.s3a.endpoint & fs.s3a.endpoint.region are empty, Spark will set fs.s3a.endpoint to 

s3.amazonaws.com here:

[https://github.com/apache/spark/blob/9a2f39318e3af8b3817dc5e4baf52e548d82063c/core/src/main/scala/org/apache/spark/deploy/SparkHadoopUtil.scala#L540] 

 

HADOOP-18908, updated the region logic such that if fs.s3a.endpoint.region is set, or if a region can be parsed from fs.s3a.endpoint (which will happen in this case, region will be US_EAST_1), cross region access is not enabled. This will cause 400 errors if the bucket is not in US_EAST_1. 

 

Proposed: Updated the logic so that if the endpoint is the global s3.amazonaws.com , cross region access is enabled.
