To temporarily turn off compactions without schema update, use
nodetool –h -p setcompactionthreshold
for every node and every column family you need.
If nodetool throws same exception, do in 2 steps:
1. nodetool setcompactionthreshold 0 32 (32 – use
yours instead)
2. nodeto
Thanks. Just figured out yesterday that I switched the snapshots mixing the
tokens.
Will try again today.
And another question. If I am putting the snapshots on a clean ring, I need
to first create the data model?
Thanks

The docs for the CLI say:
- min_compaction_threshold: The minimum number of SSTables needed
to start a minor compaction. Default is 4, setting to 0 disables minor
compactions.
If you are getting an error using 0 can you please raise a ticket on

I would bucket the time stats as well.
If you write all the attributes at the same time, and always want to read them
together, storing them in something like a JSON blob is legitimate approach.
Other Aaron, can you elaborate on

The Hinted Handoff CF;s are in the system Keyspace, the files will be in the

Did you use the same tokens for the nodes in both clusters?

Hi!
I am testing backup and restore.
I created the restore using parallel ssh on all 3 nodes.
I created a new 3 ring setup and used the snapshot to test recover.
Snapshot from every original node went to one of the new nodes.
When I compare the content of the data dir it seems that all files from t
I think as you, but this is not true, there are not any permissions
issue. And as i said before, cassandra try to create directory for
snapshort that already exists

Hi!
I wanted to test restoring my Cassandra cluster from a snapshot.
I created a new ring (with 3 nodes) same as my environment.
I started recovering one node at a time and failed with the first :)
I didn't create the schema on the new node, but I did create the cluster.
I stopped Cassandra
I cop
Hi,
We are currently running 0.8.10 with 4 nodes. We tried to re-balance the
range each node owns by using "nodetool move". After moving the node to the
assigned token, we run the cleanup command, then we saw the exceptions:
Error occured during cleanup
java.util.concurrent.ExecutionException:
