venkata ram kumar ch updated HDFS-13810:
----------------------------------------
Description:
In RBF when we try to update the existing mount entry by using the add command
its creating a mount entry by taking -order as target path.
command : ./hdfs dfsrouteradmin -add /aaa ns1 /tmp (record added to the mount
table)
Now when we use the below command on the same mount entry.
Command : hdfs dfsrouteradmin -add /aaa ns1 -order RANDOM (its not performing
the validation check for the second time).
was:
In Router based federation when we try to add the mount entry without having
the destination path, its getting added into the mount table by taking the
other parameters order as destination path.
Command : hdfs dfsrouteradmin -add /aaa ns1 -order RANDOM
its creating a mount entry by taking -order as target path
Summary: RBF: validation check was not done for adding the multiple
destination to an existing mount entry. (was: RBF: Adding the mount entry
without having the destination path, its getting added into the mount table by
taking the other parameters order as destination path.)
> RBF: validation check was not done for adding the multiple destination to an
