Hemanth Boyina created HDFS-15510:
-------------------------------------
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
