We are adding node into a cluster with some data. The new node is in
Bootstrapping mode for a long time, waiting for data to be streamed to it, but
the streaming seems to get stuck.
Mode: Normal
Streaming to: /10.110.10.10

As suggested, we did do removetoken, set autobootstrap true, initial token and
start. Now the new nodes are in the Boostrapping state for a while, but nothing

We have a cluster running in one data center, and are adding some in a new data
center. There are some data already in the current cluster.
We did something wrong at first by not having AutoBootstrap on, when we saw no
data being migrated. So we wiped out the data on the new nodes, and then start
When using nodetool move command, the streaming between nodes got stuck for a
long period like the following:

Is this normal, or did we miss something?

We have a five node cluster, using replication factor of 3. The application is

Can you turn JMX authentication on for Cassandra? I tried and it works for
jconsole, etc. But I couldn't figure out how to pass username/password to
nodetool, etc.
Anyone has tried it before?
Thanks.

We have an application that does a lot of updates to the rows. We use
replication factor of 3 and are moving to multiple data centers. We would like
to accomplish the following setup:
Data are replicated to other data centers. RackAwareStrategy seems to be able
to handle that, however
