Question about HA and Federation
Hi All,

I´m going to test a hadoop cluster and I have a doubt about HA and

With federation I Have a NameNode per namespace and with HA I have an
Active NameNode and a standby NameNode.

so, as I have sevaral namespaces, do I need an Active NameNode and a
standby nameNode per namespace?

I have read this documentation but It´s not clear for me :-(


Thanks in advance
