Missing MultiQuorumResponseHandler in current svn?
Hi, I have an up-to-date svn repository (r759176), and the build fails
with a few errors like:
[javac] trunk/src/org/apache/cassandra/service/StorageProxy.java:619: cannot find symbol
[javac] symbol : class MultiQuorumResponseHandler
[javac] location: class org.apache.cassandra.service.StorageProxy
[javac] private static MultiQuorumResponseHandler dispatchMessages(Map<String, ReadMessage[]> readMessages, Map<String, Message[]> messages) throws IOException
Perhaps did someone forget to add a file (maybe
src/org/apache/cassandra/service/MultiQuorumResponseHandler.java)
when committing?
Thanks,
Roland

Nice catch, Jun.
I created an issue in jira so we don't forget this.

The way it is today the hinted rows stay in the app CF but since they are
not large in number or size it should not be an issue.
The reason for this is that deletes does not work yet in cassandra and it
needs to be fixed unless all compactions are run immediately after deleting
hence deletion of
hints themselves works. But this is ofcourse not possible in App CFs.
Also the way we clean up the hinted keys from the app CF and other keys
which can get accumulated over time due to machine splits etc is by running
a Cleanup process
which goes through all the files and throws away unnecessary keys .
Thanks

In HintedHandoff.runDeliverHints(), after the hints are delivered, the
hinted keys are deleted from the hinted CF only, but not from the
application CF. Does that mean the hinted rows will stay in the application
CF forever? I am probably missing something here.

I committed a stub until Avinash can commit the real thing.
