I am running cassandra 0.6.6
4 nodes with RF=3
Have set the InitialTokens manually
Loaded around 4 million records
Had a question why the following is happening
Node 4 was down when a new key 1005 was added (value 123).
Node 2 which is responsible for the key added a Hint for Node 4
Node 4 was
To keep the question simple,
If an insert or remove Key happens when the responsible Node is down
(RF=3) what is the expected behavior when the Node comes back up ?
For example Key 1005 was removed when Node 2 was down. When Node 2
came back up it started showing back ?

My findings - would be nice if somebody can please verify.
Critical for our eval to verify HintedHandOff, ReadRepair and
AntiEntropy works as we think it does
Node 1, 2, 3, 4
RF=3
All nodes up - Node 2 is responsible for key 1005
Write CL=ONE, Insert key 1005, value=123 in Node 1
Node 2, 3, 4

Your expectation is
You constructed a pathological case and then got confused at the result.
Consider instead a realistic case: RF=3, CL=QUORUM. Writes should go
to all of A, B, and C. B is down when the write request arrives, so
does not acknowledge the it. A and C acknowledge the write. Since
quorum is
The answer of Benjamin is very right.

Hi all,
Please consider this case: (RF=1, CL=ONE)
1. I have A, B and C nodes.
2. A node is a coordinator node, it sends a request to B node to do write
operation.
3. B node is down during write operation, so return failure message to
client, and write a hint to C node.
4. B node comes
So, am I correctly?

If so, when does hinted handoff work?
