Xiaoyu Yao commented on HDFS-9240:
----------------------------------
I just recheck the compatibility guideline. Since the BlockLocation class is
annotated with Public/Stable, should we deprecate the telescope constructors
instead of removing them completely so that this change won't break downstream
projects that have dependency on it?
https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#Policy
"Public-Stable API compatibility is required to ensure end-user programs and
downstream projects continue to work without modification."
> Use Builder pattern for BlockLocation constructors
