Miklos Szegedi commented on YARN-7712:
--------------------------------------
Thank you, [~chris.douglas] for the reply.
Here are my requirements:
1. I would like to run my own YARN AM in an unmodified cluster, so I believe I
cannot use FilterFileSystem
2. The option to ignore the timestamp should be application specific (no global
config, etc.)
3. I have no client code in Java, so only REST APIs can be used
Given the above requirements 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. This is why it would be nice to have a special
value (-1) to ignore the timestamp per request. The default remains the same,
no other applications are affected.

> 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.
