Hi everyone
Seems this breaks,
{{TestHdfsConfigFields.testCompareConfigurationClassAgainstXml}}
Failed in this PR as well,
https://builds.apache.org/job/hadoop-multibranch/job/PR-2156/3/testReport/org.apache.hadoop.tools/TestHdfsConfigFields/testCompareConfigurationClassAgainstXml/
This required addition in {{hdfs-default.xml}}, it was mentioned in the PR, it
would be done as part of HDFS-15480, But I don't find that being done there as
well.

> Ordered snapshot deletion is a configurable feature. In this JIRA, a conf is
> added.
> When the feature is enabled, only the earliest snapshot can be deleted. For
> deleting the non-earliest snapshots, the behavior is temporarily changed to
> throwing an exception in this JIRA. In HDFS-15480, the behavior of deleting
> the non-earliest snapshots will be changed to marking them as deleted.
