coordinator failure handling

[amit sehas]

Sorry to bother you, i am just starting to look into Cassandra, and am confused 
about a lot of things.
If a client sends a query to a coordinator, then if it does not receive a 
response from the co-ordinator then:
a) is there a timeout at which client retries the query?b) is there somewhere 
we can specify the timeout?c) will it resend the query to the same 
co-ordinator, if not then how does it determine which coordinators to send it 
to?
thanks
