executed the scrub command, but after restarting both of my nodes I got

Hi,
Is it possible to restore a snapshot of a keyspace on a live
cassandra cluster (I mean without restarting)?
Actually that's wrong, it is perfectly possible to restore a snapshot
on a live cassandra cluster.
There is even basically 2 solutions:
1) use the sstableloader (http://www.datastax.com/dev/blog/bulk-loading)
2) copy the snapshot sstable in the right place and call the JMX
method loadNewSSTables()
Great! I will use the hardlinks to 'restore' the data files on each node (super
fast)!
I have some related questions :
1) I assume that I have to call the loadNewSSTables() on each node?
2) To be on the save side, I guess I better drop the existing keyspace and then
recreate using the

this is same as nodetool refresh?
We want to store a large number of columns in a single row (up to about
100,000,000), where each value is roughly 10 bytes.
We also need to be able to get slices of columns from any point in the row.
We haven't found a problem with smaller amounts of data so far, but can anyone
think of any
Then http://www.datastax.com/docs/1.1/operations/backup_restore should

I've been using the cql3 to create a composite table.
Can I use the thrift interface to accomplish the
same thing? In other words, do I have to use cql 3 to
get a composite table type? (The same behavior as
multiple PRIMARY key columns).
Thanks,

For how to do it with astyanax, you can see here...

I use it on that project for indexing
What is the process for joining a new data center to an existing cluster as DR?
We have a 5 node cluster in our primary DC, and want to bring up 5 more in our
2nd data center purely for DR. How should these new nodes be joined to the
cluster and be seen as the 2nd data center? Do the new
