problem with write_survey
Hello,
I start a node with the write survey = true
-Dcassandra.write_survey=true
Log:
INFO [main] 2015-07-29 15:29:35,697 StorageService.java (line 853) Startup complete, but write survey mode is active, not becoming an active ring member. Use JMX (StorageService->joinRing()) to finalize ring joining.
but the node allows read:
cqlsh> select * from myTable where id = 1745;
id | fname | lname
------+-------+-------
1745 | john | smith
(Key 1745 exists on node with the the write survey = true)
Then, when attempting a transition a node from write survey to normal mode, the "nodetool join" invocation fails as the node is already "joined".
Do you have any idea ?
Cassandra Version: 2.0.10

If that's the case, I would upgrade to the most recent 2.0.x release, see
if you can reproduce the behavior on that version. If you can, file a JIRA
(and respond to the thread to close the loop so we know what JIRA it is!)...

This is unexpected. Does the node show up in eg nodetool ring? If so, you are probably failing to properly use write_survey.
