Ivo Ladage - van Doorn commented on AMDATU-254:
-----------------------------------------------
I patched Cassandra with the patch attached to
https://issues.apache.org/jira/browse/CASSANDRA-1992 and tried again. But with
this patch applied, Cassandra doesn't start at all. It fails with this error:
Exception encountered during startup.
java.lang.NoSuchFieldError: instance

I also tried downloading the latest cassandra from the Hudson server but ran
into the exact same issue. So we will have to wait until there is 0.7.1 until
we can test if this issue is resolved. Moving to 0.1.1.

> Key: AMDATU-254
> URL: http://jira.amdatu.org/jira/browse/AMDATU-254
> Project: Amdatu
> Issue Type: Bug
> Components: Amdatu Cassandra
> Affects Versions: 0.1.0
> Reporter: Ivo Ladage - van Doorn
> Assignee: Ivo Ladage - van Doorn
> Fix For: 0.1.1
>
>
> The following use case causes random data to disappear from the cassandra
> storage:
> - Start a node in the cassandra cluster with replication factor 1
> - Start another node in the cassandra cluste, also with replication factor 1
> Now apparently, bringing up the second node in the cluster causes random data
> to be removed from the Role ColumnFamily. After bringing up the first node,
> these are the row keys available in the CF 'Role';
> (1) user_marior
> (2) user_janed
> (3) group_Parent
> (4) user_melissad
> (5) group_Student
> (6) group_Administrators
> (7) user_georged
> (8) user_tedb
> (9) group_Teacher
> (10) user_elisad
> (11) user_Administrator
> (12) user_maijam
> (13) user_johnd
> After booting the second node, random data disappeared:
> (1) user_marior
> (2) group_Teacher
> (3) user_elisad
> (4) user_Administrator
> (5) user_maijam
> (6) user_johnd
> the result is different every time you try it. Also, when I stop node 2,
> clean its cassandra database and start it again, more data is missing.
