Hi,
we have 4 node Cassandra (version 0.8.1) cluster. 2 CF inside. While first
CF is working properly (read/store), get_range_slices query on second CF
return NPE error.
Any idea why it happen? Maybe some known bug and fixed in 0.8.3 ?

Sure I can fill in the ticket. Here is what I have noticed so far, the count
of HH is not going up, which is good. I think what must have happened is
that after I restarted the cluster, no new hints were added just the old
one's are still around and not cleaned up, is that possible? Cannot say for
Update:
I scaled my cluster down from 7 nodes to 3 nodes, and kept RF=3. I did
a complete cluster rebuild, so everything was fresh. Kept my reads and
writes at CL.ALL. For a while there it seemed like I had succeeded in
eliminating the problem. Unfortunately about an hour ago a duplicate
came thro
How does range scan work in Cassandra? Does the read of a key perform the
read across all the SSTables that contain the key and return the row or are
SSTables processed sequentially? If I have a key k and its columns are
spread across N SSTables then does the read of key k return the row with all
