Description

It seems that there is a race condition in the compaction process vs AntiEntropy Streams. We often have repairs tossing lots of exceptions in the logs as follows:

Now about 1-2 minutes before that, I see Secondary Index buildup and compaction which does compact the same SSTable to a new one.

Now, does this make the repair sessions to fail? It seems the node was trying to stream a file to a node being repaired but apparently it did not.
