> Distcp -update between different cloud stores to use modification time while
> checking for file skip.
> ----------------------------------------------------------------------------------------------------
>
> Key: HADOOP-18596
> URL: https://issues.apache.org/jira/browse/HADOOP-18596
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools/distcp
> Reporter: Mehakmeet Singh
> Assignee: Mehakmeet Singh
> Priority: Major
> Labels: pull-request-available
>
> Distcp -update currently relies on File size, block size, and Checksum
> comparisons to figure out which files should be skipped or copied.
> Since different cloud stores have different checksum algorithms we should
> check for modification time as well to the checks.
> This would ensure that while performing -update if the files are perceived to
> be out of sync we should copy them. The machines between which the file
> transfers occur should be in time sync to avoid any extra copies.
> Improving testing and documentation for modification time checks between
> different object stores to ensure no incorrect skipping of files.
