Alexander Sterligov commented on CASSANDRA-6285:
------------------------------------------------
[~xedin] That NPE happend once and unfortunatelly I have not saved it. If I'll
get it once more I'll save this sstable.
I totally removed OpsCenter keyspace (with sstables) and recreated them. I
don't get "Last written key DecoratedKey" any more. By the way, this error
definetely causees streams to hang on 100%.
I have several strange things happening now:
- I've noticed that it takes about 30 minutes between "nodetool repair" and
first pending AntiEntropySession. Is that ok?
- Repair is already running for 24 hours (~13GB per node, 17 nodes). What's
the number of AntiEntropySessions to finish single repair? Number of key ranges?

- Some validation compactions run for more than 100% (1923%). I thinks that
it's CASSANDRA-7239, right?
