### Description of PR
https://issues.apache.org/jira/browse/HDFS-16762
AS the default value of
**_dfs.federation.router.client.allow-partial-listing is true_**, the hdfs
client will got partial result when one or more of the subclusters are
unavailable for no permissions or other Exceptions, but **_user may not
know_**. It will lead to some fault.
So I think it's better to make the default value as false.
