Do we have mailing lists other than yarn-dev to reach downstream developers?
It would be better to make it confident that old hamlet of Hadoop 3 is
used nowhere.
I'm +1 on making imcompatible change if this blocks another Java
migration issues,
while I don't see strong reason to hurry as I see the patch of YARN-9279.

Hi folks,
I'd like to remove the deprecated hamlet package to reduce the maintenance cost.
The old hamlet package has one character '_' and it is banned in Java
9+, so HADOOP-11875 deprecated this package and created a profile in
pom.xml not to compile the package when the Java version is 9+. After
the deprecation, we still have to maintenance the profile (see
YARN-8123 and HADOOP-16046).
The only usage I can see is Apache Slider, however, the
functionalities of Apache Slider have been merged into YARN. Therefore
I think there are no people using Slider with Hadoop 3.1+ and we can
remove the package in 3.3+.
Any thoughts?
Regards,
Akira
