Summary: Improve the validation for tolerated volumes
Key: HDFS-10279
URL: https://issues.apache.org/jira/browse/HDFS-10279
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Lin Yiqun

Now the misconfiguration for dfs.datanode.failed.volumes.tolerated are detected
too late and not easily be found. We can move the validation logic for
tolerated volumes to a eariler time that before datanode regists to namenode.
And this will let us detect the misconfiguration soon and easily.
