Ivo Ladage - van Doorn commented on AMDATU-254:
-----------------------------------------------
I could reproduce the issue with a plain cassandra 0.7 downloaded from the
site, with no modifications at all. Just before creating an issue for it in the
Apache Cassandra JIRA someone else raised the exact same issue:
https://issues.apache.org/jira/browse/CASSANDRA-1992
So apparently this is a known cassandra issue.
> When a new cassandra node comes available in the cluster, random data is
> removed from the Role ColumnFamily

> 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: 0.1.0
>
>
> 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.
