Hi,
I'm going to add a new data center DC3 to an existing cassandra cluster
which has already 2 data centers DC1 , DC2.
The thing I'm worried of is about tables in one keyspace which has QUORUM
reads and NOT LOCAL_QUORUM.
So while adding a new data centers with auto_bootstrap:false and 'nodetool

I started decommssioned a node in our cassandra cluster.
But its taking too long time (more than 12 hrs) , so I would like to

cause any issues to cluster?

connectivity issues/some other issues hints shoot upto GBs/node.
So I would like to monitor hints throughput/pin point the reason for

We have c* 2.0.17 cluster with 2 DCs - DC1, DC2. We tried to add new data
center DC3 and ran "nodetool rebuild 'DC1'" and we faced below exception on
few nodes after some data got streamed to new nodes in new data center DC3.

Even we are facing Streaming timeout exceptions during 'nodetool rebuild' ,
I set streaming_socket_timeout_in_ms to 8640 (24 hours) as suggested in

You mean to say instead of
*COPY keyspace1.columnFamily1 FROM 'dump_data.csv' WITH TTL = '7200';*use
*COPY keyspace1.columnFamily1 FROM 'dump_data.csv'

I tried this way too, but again exception thrown saying "*Unrecognized COPY
