-------------------------------------------
Summary: nodes should go into hibernate when join_ring is false
Key: CASSANDRA-6961
URL: https://issues.apache.org/jira/browse/CASSANDRA-6961
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Brandon Williams
Assignee: Brandon Williams
Fix For: 2.0.7
The impetus here is this: a node that was down for some period and comes back
can serve stale information. We know from CASSANDRA-768 that we can't just
wait for hints, and know that tangentially related CASSANDRA-3569 prevents us
from having the node in a down (from the FD's POV) state handle streaming.
We can *almost* set join_ring to false, then repair, and then join the ring to
narrow the window (actually, you can do this and everything succeeds because
the node doesn't know it's a member yet, which is probably a bit of a bug.) If
instead we modified this to put the node in hibernate, like replace_address
does, it could work almost like replace, except you could run a repair
(manually) while in the hibernate state, and then flip to normal when it's done.
This won't prevent the staleness 100%, but it will greatly reduce the chance if
the node has been down a significant amount of time.
