Hi Rahul,
Yes, it is possible. Here are the sample configurations.
===========================================
dfs.nameservices=ns1,ns2
dfs.ha.namenodes.ns1=nn1,nn2
dfs.ha.namenodes.ns2=nn1,nn2
dfs.namenode.rpc-address.ns1.nn1=ns1nn1:8020
dfs.namenode.rpc-address.ns1.nn2=ns1nn2:8020
dfs.namenode.http-address.ns1.nn1=ns1nn1:9870
dfs.namenode.http-address.ns1.nn2=ns1nn2:9870
dfs.namenode.rpc-address.ns2.nn1=ns2nn1:8020
dfs.namenode.rpc-address.ns2.nn2=ns2nn2:8020
dfs.namenode.http-address.ns2.nn1=ns2nn1:9870
dfs.namenode.http-address.ns2.nn2=ns2nn2:9870
dfs.client.failover.proxy.provider.ns1=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider
dfs.client.failover.proxy.provider.ns2=org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider
dfs.namenode.shared.edits.dir.ns1=qjournal://ns1jn1:8485;ns1jn2:8485;ns1jn3:8485/ns1
dfs.namenode.shared.edits.dir.ns2=qjournal://ns2jn1:8485;ns2jn2:8485;ns2jn3:8485/ns2

Hi,
Is it possible in the current architecture of HDFS to have multiple
nameservices(federation), with Active and Backup Namenode(HA) for each of the
nameservices?
Thanks,
Rahul
