             Summary: s3a rename onto existing file must fail
                 Key: HADOOP-13823
                 URL: https://issues.apache.org/jira/browse/HADOOP-13823
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 2.7.3
            Reporter: Steve Loughran
            Assignee: Steve Loughran
            Priority: Critical


HIVE-15199 shows that s3a allows rename onto an existing file, which is something HDFS, azure and s3n do not permit (though file:// does). This is breaking bits of Hive, is an inconsistency with HDFS and a regression compared to s3n semantics.

I propose: rejecting the rename on a file -> file rename if the destination exists (easy) and changing the s3a.xml contract file to declare the behavior change; this is needed for {{AbstractContractRenameTest.testRenameFileOverExistingFile}} to handle the changed semantics.
