----------------------------------
Assignee: Stu Hood
> Repair should never reuse a tree
> --------------------------------
>
> Key: CASSANDRA-640
> URL: https://issues.apache.org/jira/browse/CASSANDRA-640
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 0.5
> Reporter: Stu Hood
> Assignee: Stu Hood
> Fix For: 0.5
>
>
> AEService currently 'caches' MerkleTrees that have been generated by the
> local node, and can respond to a request for a tree with a cached version.
> This means that despite possibly having performed a repair, the two nodes
> will still be holding cached trees, and can respond to one another with the
> cached version, resulting in redundant repairs.
> Rather than a cache, the map of trees is intended to be a rendezvous point
> for two nodes to exchange relatively up-to-date trees. A map still might
> work, but other synchronization objects should be explored.
