Prabhu Joseph commented on YARN-9558:
-------------------------------------
Thanks [~adam.antal] for the review. Have attached [^YARN-9558-003.patch]
addressing above review comments.
Regarding backward compatibility,
yarn.nodemanager.remote-app-log-dir-include-older config is introduced which by
default is true, i.e, Application Log Reader will fetch the logs for a given
application from older app log dir structure (before YARN-6929) along with new
log dir structure. Writer won't have an issue as it writes to assigned app log
dir structure. Have tested the reader logic with both new and old dir
structure, it works as expected.
