I got the following exception when i was trying to decommission a live node. 
There is no reference in the manual saying that i need to stop the data coming 
into this node. Even then, decommissioning is specified for live nodes.

Can anyone let me know if am doing something wrong or if this is a bug on 
cassandra part?

Cassandra Version Used : 2.0.3
