------------------------------------

             Summary: Make the default value of 
dfs.federation.router.client.allow-partial-listing as false.
                 Key: HDFS-16762
                 URL: https://issues.apache.org/jira/browse/HDFS-16762
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: rbf
            Reporter: Chengwei Wang
            Assignee: Chengwei Wang


 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.
