[jira] [Commented] (CASSANDRA-4118) ConcurrentModificationException in ColumnFamily.updateDigest(ColumnFamily.java:294) (cassandra 1.0.8)

We've been testing this configuration for like 2 months and all seems to be working fine. We use org.apache.cassandra.dht.RandomPartitioner. Is that a must to use the lucandra partitioner?

The fact that Solandra has been (from what I understand) mostly tested on 0.8 and that on 0.8 this ConcurrentModificationException wouldn't be triggered (due to internal changes) also help pointing towards this direction. So IMO there is a very good change that this is a case of Solandra not being 1.0 ready.
