-------------------------------------------
Ping [~azotcsit]
> Truncate operation doesn't delete rows from HintsColumnFamily.
> --------------------------------------------------------------
>
> Key: CASSANDRA-4655
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4655
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.0
> Environment: Centos 6.2, Cassandra 1.1.4 (DataStax distribution),
> three-nodes cluster.
> Reporter: Alexey Zotov
> Assignee: Alexey Zotov
> Priority: Minor
> Labels: hintedhandoff, truncate
> Fix For: 1.2.4
>
> Attachments: cassandra-1.2-4655-hints_truncation.txt,
> cassandra-1.2-4655-hints_truncation-v2.txt
>
>
> Steps to reproduce:
> 1. Start writing of data to some column family, let name it 'MyCF'
> 2. Stop 1 node
> 3. Wait some time (until some data will be collected in HintsColumnFamily)
> 4. Start node (HintedHandoff will be started automatically for 'MyCF')
> 5. Run 'truncate' command for 'MyCF' column family from command from cli
> 6. Wait until truncate will be finished
> 7. You will see that 'MyCF' is not empty because HintedHandoff is copying
> data
> So, I suggest to clean HintsColumnFamily (for truncated column family) before
> we had started to discard sstables.
> I think it should be done in CompactionManager#submitTrucate() method. I can
> try to create patch but I need to know right way of cleaning
> HintsColumnFamily. Could you clarify it?
