--------------------------------------
Summary: AmazonS3Client.deleteObjects() need to be limited to 1000
entries per call
Key: HADOOP-10714
URL: https://issues.apache.org/jira/browse/HADOOP-10714
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Affects Versions: 2.4.0
Reporter: David S. Wang
Assignee: David S. Wang

error similar to:

Note that this is mentioned in the AWS documentation:
http://docs.aws.amazon.com/AmazonS3/latest/API/multiobjectdeleteapi.html
"The Multi-Object Delete request contains a list of up to 1000 keys that you
