[jira] [Created] (CASSANDRA-2368) Cassandra loses rows when a new
node is added to the cluster
Cassandra loses rows when a new node is added to the cluster
------------------------------------------------------------
Key: CASSANDRA-2368
URL: https://issues.apache.org/jira/browse/CASSANDRA-2368
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.7.4
Reporter: Markus Wiesenbacher
Hi,
I have a node with some column families each containing 1 row with several columns. Now I setup a new node (AutoBootStrap = false) and get the scheme/data. If I check both nodes for the rows, some rows are missing.
Best regards
Markus

[jira] [Resolved] (CASSANDRA-2368) Cassandra loses rows when a new
node is added to the cluster

Jonathan Ellis resolved CASSANDRA-2368.
---------------------------------------
Resolution: Not A Problem
autobootstrap=false means "don't transfer the data to the new node, that should belong to it." so you should set it to true when adding nodes to a cluster with data in it. see http://wiki.apache.org/cassandra/Operations

The old node will route queries to the new node too.

------------------------------------------------
I am not sure if you understand me correctly. My new node didn't have any data and some old rows don't appear anymore, not on the old not on the new node.

Markus Wiesenbacher commented on CASSANDRA-2368:
------------------------------------------------
Just to get sure that everybody understands my problem:
1. Node1 has some column families where each contains one row.
2. I set up a fresh Node2 (no data), leave AutoBootStrap on false.
3. I can search on both nodes, but some rows are not found on Node1 and not on Node2.
So my question is: Where are they? Maybe I don´t understand some principles of Cassandra ..
My next step is to try to decommission Node2, maybe my data comes back.

But I can´t find the rows on the existing node anymore, where have they gone to?
