Jun Rao updated CASSANDRA-34:
-----------------------------

    Attachment: issue34.patch_v1

Attach a fix. About the patch.

1. Make sendMessage blocking.
2. Delete the rows in application CF after hinted data is sent. To do that, we need to collect the largest timestamp among columns in a CF and then delete the CF with the largest timestamp.
3. When a column is in a deleted CF and their timestamps are the same, the rule is that the deleted CF wins. This rule is needed for step 2 above. Change CFStore.removeDeleted according to this rule.

> from the list: "after the hints are delivered, the hinted keys are deleted from the hinted CF only, but not from the application CF."
> Prashant verified that this is a bug that can't be fixed until deletes are fully working.
> Note: when we fix this, see if we can do so w/o compromising the immediate-GC of the hinted CF keys.
