Stu Hood commented on CASSANDRA-924:
------------------------------------
> why does the test patch add endpoints.add to forceTableRepair?
Rather than implementing the neighbor calculation in two places, I wanted to
reuse the logic in AES. In addition to the neighbors, forceTableRepair sends a
tree request to localhost, so we add it back to the neighbor list.

> With Replicationfactor=2, if a server is brought down and its data directory
> wiped out, it doesn't restore its data replica after restart and nodeprobe
> repair.
> Steps to reproduce:
> 1) Bring up a cluster with three servers cs1,2,3, with their initial token
> set to 'foo3', 'foo6', and 'foo9', respectively. ReplicationFactor is set to
> 2 on all 3.
> 2) Insert 9 columns with keys from 'foo1' to 'foo9', and flush. Now I have
> foo1,2,3,7,8,9 on cs1, foo1,2,3,4,5,6, on cs2, and foo4,5,6,7,8,9
> on cs3. So far so good
> 3) Bring down cs3 and wipe out its data directory
> 4) Bring up cs3
> 5) run nodeprobe repair Keyspace1 on cs3, the flush
> At this point I expect to see cs3 getting its data back. But there's nothing
> in its data directory. I also tried getting all columns with
> ConsistencyLevel::ALL to see if that'll do a read pair. But still cs3's data
> directory is empty.
