Timestamps on S3

Timestamps of objects and directories in Amazon S3 do not follow the behavior of files and directories in HDFS:

  • The creation time of an object is the time when the object was created in the object store. This is at the end of the write process, not in the beginning.

  • If an object is overwritten, the modification time is updated.

  • Directories may or may not have valid timestamps.

  • The atime access time feature is not supported by any of the object stores found in the Apache Hadoop codebase.
