David ;
bring down all the nodes with the exception of the 'seed' node.Now bring up the
10th node. Run 'nodetool status' and wait until this 10th node is UP. Bring
up the rest of the nodes after that. Run 'nodetool status' again and check
that all the nodes are UP.
Alternatively;decommission the 10th node completely.drop it from the Cluster.
Build a new node with the same IP and hostname and have it join the running
cluster.
hope this helpsJan

Alain, We still have the timeout problem in OPSCenter and we still didn’t
solve this problem so no we didn’t ran an entire repair with the repair
service. And yes, during this try, we’ve set auto_bootstrap to true and ran a
repair on the 9th node after it finished streaming. Thank you for your help.
Best regards,

Objet : Re: Stream failure while adding a new node Hi David, Are you sure
you ran the repair entirely (9 days + repair logs ok on opscenter server)
before adding the 10th node ? This is important to avoid potential data loss !
Did you set auto_bootstrap to true on this 10th node ? C*heers, Alain

<david.charbonn...@rgsystem.com>: Hi, We’re using Cassandra 2.0.8.39 through
Datastax Enterprise 4.5.1 with a 9 nodes cluster. We need to add a few new
nodes to the cluster but we’re experiencing an issue we don’t know how to
solve. Here is exactly what we did : - We had 8 nodes and need to add a
few ones - We tried to add 9th node but stream stucked a very long time
and bootstrap never finish (related to streaming_socket_timeout_in_ms default
value in cassandra.yaml) - We ran a solution given by a Datastax’s
architect : restart the node with auto_bootstrap set to false and run a repair
- After this issue, we ran into pathing the default configuration on
all our nodes to avoid this problem and made a rolling restart of the cluster -
Then, we tried adding a 10th node but it receives stream from only one
node (node2). Here is the logs on this problematic node (node10) : INFO

Did you ran into this issue or do you have any idea on how to solve this ?
Thank you for your help. Best regards,
