Thanks [~ayushtkn] for ping.
{quote}I started reading but got an initial doubt, regarding the need to split
read and write routers. I think we can use only one kind of routers itself.

I am also thinking to utilize same router for observer call instead adding new
role for router. It will increase complexity of cluster. Already HDFS
overloaded with different role of processes.
