Richard Low updated CASSANDRA-2947:
-----------------------------------
Attachment: 2947.txt
> New nodes always think dead nodes are alive
> -------------------------------------------
>
> Key: CASSANDRA-2947
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2947
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 0.8.2
> Reporter: Richard Low
> Attachments: 2947.txt
>
>
> If a new node is brought up while a node is down, it will think it is up
> forever.
> To reproduce:
> Take nodes A, B and C.
> 1. Bring up nodes A and B in a cluster
> 2. Take down B and wait for A to mark it as down
> 3. Bring up C with A as a seed
> 4. nodetool ring on C shows all 3 nodes as up and never marks B as down
> The problem is that the failure detector never learns about node B -
> FD.report is never called for B. This means requests are constantly routed
> to B from C and timeout, but they should fail with UnavailableException.
> The attached (hack) patch appears to fix it, but I expect the problem is
> actually elsewhere in the gossip code.
