Lin Yiqun commented on HDFS-10279:
----------------------------------
The failed unit test {{TestFsDatasetImpl}} is caused by
{{TestFsDatasetImpl.testCleanShutdownOfVolume}} which tracked by HDFS-10260,
the other failed tests seem not related.
> Improve the validation for tolerated volumes

> Now the misconfiguration for dfs.datanode.failed.volumes.tolerated are
