[jira] [Created] (HDFS-11109) ViewFileSystem Df command should work
even when the backing NameServices are down
Manoj Govindassamy created HDFS-11109:
-----------------------------------------
Summary: ViewFileSystem Df command should work even when the backing NameServices are down
Key: HDFS-11109
URL: https://issues.apache.org/jira/browse/HDFS-11109
Project: Hadoop HDFS
Issue Type: Task
Affects Versions: 3.0.0-alpha1
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
With HDFS-11058, Df command will work well with ViewFileSystem. federated cluster can be backed up several NameServers, with each managing their own NameSpaces. Even when some of the NameServers are down, the Federated cluster will continue to work well for the NameServers that are alive.
But {{hadoop fs -df}} command when run against the Federated cluster expects all the backing NameServers to be up and running. Else, the command errors out with exception.
Would be preferable to have the federated cluster commands highly available to match the NameSpace partition availability.
