             Summary: RBF: Quota and Content Summary was not correct in Multiple Destinations
                 Key: HDFS-15510
                 URL: https://issues.apache.org/jira/browse/HDFS-15510
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Hemanth Boyina
            Assignee: Hemanth Boyina


steps :

*) create a mount entry with multiple destinations ( for suppose 2)

*) Set NS quota as 10 for mount entry by dfsrouteradmin command, Content Summary on the Mount Entry shows NS quota as 20

*) Create 10 files through router, on creating 11th file , NS Quota Exceeded Exception is coming 

though the Content Summary showing the NS quota as 20 , we are not able to create 20 files

 

the problem here is router stores the mount entry's NS quota as 10 , but invokes NS quota on both the name services by set NS quota as 10 , so content summary on mount entry aggregates the content summary of both the name services by making NS quota as 20
