There have been two similar reports in the last few days.

The joining node is unable to discover the cluster information it needs to find the correct
place to join. However there code appears to have checks in place to prevent that from happening.

If you have time can you please try to reproduce the fault ?
* set logging to DEBUG on /etc/cassandra/log4j-server.properties
* clear all files from /var/lib/cassandra/data/system
* start the node

I *think* if you restart the node it will work as it will used stored load data. But I'm unsure
if it will bootstrap as that only happens once, you may want to run a repair.

Cheers

I am using storage port 7000 (deafult) across all nodes.

Do you use same storage_port across 3 nodes?
Can you access to the storage_port of the seed node from the last (failed) node?

I was able to successfully join a node to already existing one-node
cluster (without giving any intital_token), but when I add another
machine with identical settings (with changes in listen broadcast and
rpc address). I am unable to join it to the cluster and it gives me following error:



INFO 17:50:35,555 JOINING: schema complete, ready to bootstrap

INFO 17:50:35,556 JOINING: getting bootstrap token

java.lang.RuntimeException: No other nodes seen!  Unable to
bootstrap.If you intended to start a single-node cluster, you should
make sure your broadcast_address (or listen_address) is listed as a
seed.  Otherwise, you need to determine why the seed being contacted
has no knowledge of the rest of the cluster.  Usually, this can be
solved by giving all nodes the same seed list.

Now when I put some interger value to intial_token  the Cassandra
starts working but is not able to connect to the main cluster which
became evident from the command Nodetool -h <ip of this node> ring. It
displayed itself with 100% ownership.





Kindly help me with it asap.

Rishabh
