> Hi,
> First off I am sorry if the component is not right for this.
> I am trying to get the point-in-time backup to work. And I ran into the
> following issues:
> 1. The documentation in the commitlog_archiving.properties seems to be out of
> date, as the example date format is no more valid and can't be parsed.
> 2.
> The restore_point_in_time property seems to differ from the actual
> maxTimeStamp. I added additional logging to the codebase in the class
> CommitLogReplayer like that:
> protected boolean pointInTimeExceeded(RowMutation frm)
> {
> long restoreTarget = CommitLog.instance.archiver.restorePointInTime;
> logger.info(String.valueOf(restoreTarget));
> for (ColumnFamily families : frm.getColumnFamilies())
> {
> logger.info(String.valueOf(families.maxTimestamp()));
> if (families.maxTimestamp() > restoreTarget)
> return true;
> }
> return false;
> }
> The following output can be seen:
> The restoreTarget timestamp is: 1377015783000
> This has been correctly parsed as I added this date to the properties:
> 2013:08:20 17:23:03
> the value for families.maxTimestamp() is: 1377009021033000
> This date corresponds to: Mon 45605-09-05 10:50:33 BST (44 millennia from now)
> It seems like the timestamp has 3 additional zeros. This also means that the
> code can never return false on the call, as the restoreTarget will always be
> smaller then the maxTimestamp(). Therefore the Replayer can never replay any
> of my commitlog files.
> The timestamp minus the 3 zeros corresponds to "Tue 2013-08-20 15:30:21 BST
> (23 hours ago)" which makes more sense and would allow for the replay to
> work.
> My config:
> Cassandra-1.2.4
> Java 1.6
> Ubuntu 12.04 64bit
> If you need any more information let me know and I'll be happy to suply
> whatever info I can.
