Vijay updated CASSANDRA-2300:
-----------------------------
Description:
Problem: When we add more than one node to the cluster, nodes tends to get the
same token range's.... currently we have to wait till the node starts to stream
the data (Stage 3 as listed below)
There are 3 stages while the node trys to bootstrap
1) It understands the Ring
2) It finds a token in the ring and announce to the cluster
3) Start to stream the data.
Possible Solution: If we can move the stage 2 from the bootstrapping node to
the seed node's, when it starts the boot strapping it will be easier for the
other nodes who are joining.
This will reduce the time which is needed for us to add nodes to the clusters.
This will also reduce the manual work of assigning the tokens when doubling the
cluster and opens up possibilities of future enhancements to the token
assignment.
