Chris Douglas commented on YARN-7712:
-------------------------------------
bq. I need to use webhdfs to get the timestamp and set for each localized file
every time I launch something. This is cumbersome and not necessary in case of
my app
Perhaps, but YARN doesn't have anything else for correctness. If you're
convinced this is necessary, please ensure that the NM verifies that the
timestamp for a cached dependency matches the remote, before it returns it to
the client (so if it's changed, the app gets the new version, never the cached
version). To be consistent, you may also want to add similar semantics for size.

> YARN currently requires and checks the timestamp of localized files and
> fails, if the file on HDFS does not match to the one requested. This jira
> adds the ability to ignore the timestamp based on the request of the client.
