-----------------------------------------------
Hhmm, second time I tried this with the same setup but clean boot other things
happen:
- On node 2 I get an error after the 2 minute timeout:
DEBUG: Found 22 keys for ColumnFamily 'Gadget' in getRowKeys

- After a restart of both nodes the data is back again
- When I change replication factor from 2 to 1, sometimes I get
TimedOutExceptions.

> 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.
