[jira] Commented: (CASSANDRA-1992) Bootstrap breaks data stored
(missing rows, extra rows, column values modified)
[ https://issues.apache.org/jira/browse/CASSANDRA-1992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12982181#action_12982181 ]
Mateusz Korniak commented on CASSANDRA-1992:
--------------------------------------------
Not sure if it is important but:
After loading data ring looks like:
Address Status State Load Owns Token
192.168.3.4 Up Normal 59.02 KB 100.00% 0
After bootstraping:
192.168.3.4 Up Normal 199.28 KB 56.45% 0
192.168.3.8 Up Normal 115.03 KB 43.55% 74091174110465149971373554442555361956
Load gets tripled on 1st node.

> Key: CASSANDRA-1992
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1992
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.0
> Environment: Linux 2.6.36-1 #1 SMP Tue Nov 9 09:56:02 CET 2010 x86_64 Intel(R)_Core(TM)2_Quad_CPU____Q8300__@_2.50GHz PLD Linux
> glibc-2.12-4.i686
> java-sun-1.6.0.22-1.i686
> Reporter: Mateusz Korniak
> Assignee: Brandon Williams
> Fix For: 0.7.1
>
> Original Estimate: 8h
> Remaining Estimate: 8h
>
> Scenario:
> Two fresh (empty /data /commitog /saved_caches dirs) cassandra installs.
> Start first one.
> Run data inserting program [1], run again in verify mode - all data intact.
> Bootstrap 2nd node.
> Run verification again, now it fails.
> Issue is very strange to me as cassandra works perfectly for me when cluster nodes stay the same for days now but any bootstrap ( 1 -> 2 nodes, 2 -> 3 nodes, 2->3 nodes RF=2) breaks data.
> I am running cassandra with 1GB heap size, 32bit userland on 64bit kernels, not sure what else could matter there.
> Any hints ?
> Thanks in advance, regards.
> [1] simple program generating data and later verifying data.
