Hi,

If I have four name nodes in my= cluster: n1, n2, n3, n4, then
n2 is n1's standby,=A0 n4= is n3's standby.

there is no dependency between n1 a= nd n3, which is HDFS federation.

Anybody can kindly give me an example for HA and federation = configuration? especially HDFS HA, how to configure two JN groups (dfs.n= amenode.shared.edits.dir) for n1/n2 and n3/n4, Thanks.
