Arya Goudarzi created CASSANDRA-5266:
----------------------------------------
Summary: FileNotFoundException during AntiEntropy Stream Session
after compaction
Key: CASSANDRA-5266
URL: https://issues.apache.org/jira/browse/CASSANDRA-5266
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.6
Environment: Ubuntu 10.04
Cassandra 1.1.6
Jave 6 (64 Bit Sun JVM)
Reporter: Arya Goudarzi
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.
