Subject [jira] [Commented] (CASSANDRA-12485) Always require replace_address to replace existing token
Date Mon, 17 Oct 2016 16:22:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15582661#comment-15582661
] 

Joel Knighton commented on CASSANDRA-12485:
-------------------------------------------

That should work. Regardless, it seems like the problem is not in the dtests specifically
but elsewhere. Does the {{stress-build}} step complete properly when you run {{ant clean jar}}?
Can you run the Cassandra Stress binaries manually? (tools/bin/cassandra-stress)

> CASSANDRA-10134 prevented replace an existing node unless {{\-Dcassandra.replace_address}}
or {{\-Dcassandra.allow_unsafe_replace=true}} is specified.
> We should extend this behavior to tokens, preventing a node from joining the ring if
another node with the same token already existing in the ring, unless {{\-Dcassandra.replace_address}}
or {{\-Dcassandra.allow_unsafe_replace=true}} is specified in order to avoid catastrophic
scenarios.
> One scenario where this can easily happen is if you replace a node with another node
with a different IP, and after some time you restart the original node by mistake. The original
node will then take over the tokens of the replaced node (since it has a newer gossip generation).
