Lyuben Todorov updated CASSANDRA-5351:
--------------------------------------
Attachment: node3.log
node2.log
node1.log
I've attached the logs from the 3 nodes (only the parts generated from repair)
logs from node2 and 3 are the interesting ones (log1 is info only). The repair
was first initiated on node 3 and completed sucessfully, but then when launched
for node2 stalled after the first repair session completed at the assertion @
DataTracker#newSSTables
> Avoid repairing already-repaired data by default
> ------------------------------------------------

> Repair has always built its merkle tree from all the data in a columnfamily,
> which is guaranteed to work but is inefficient.
> We can improve this by remembering which sstables have already been
> successfully repaired, and only repairing sstables new since the last repair.
> (This automatically makes CASSANDRA-3362 much less of a problem too.)
> The tricky part is, compaction will (if not taught otherwise) mix repaired
> data together with non-repaired. So we should segregate unrepaired sstables
> from the repaired ones.
