Hi Andras,
I am not using a VPN. The system has been running successfully in this
configuration for a couple of weeks until I noticed the repair is not
working.
What happens is that I configure the IP Tables of the machine on each
Cassandra node to forward packets that are sent to any of the IPs
Hi,
I am running into some problems with secondary indexes that I am unable to
track down. When I restart the cassandra service, the secondary index data
won't load and I get the following error during startup:

Hi
please refer JDK nio package's ByteBuffer, I don't think that ByteBuffer
can be cast from the BigInteger directly,
it seems you need make some conversion before put it into a ByteBuffer.
Thanks

Dear all,
I am trying to understand whether I can fasten the retrieval process using
cache. Please can you help me write the code for setting the cache properties
in Cassandra.
Please help

Hi,
but if the data must be converted, this is something that should be fixed
inside cassandra… Is this a bug, should I file a bug report?
Or is there some kind of setting I can change to make it work for now?
Maybe it is related to this issue, but this should have been fixed in 1.1.0:

Thanks for the reply. Should have thought about looking into the log files
sooner. An AssertionError happens at execution. I haven't figured out yet why.

Since Cassandra optimizes and sends only one copy over the WAN, can I opt
in only for HH for WAN replication and avoid HH for the local quorum?
(since I know I have more copies)

After enable Cassandra debug log, I got following log, it shows the
delete mutation send to other two nodes rather then local node.
And then the read command come to the local nodes.
And local one found the mismatch.
But I don't know why local node return the local dirty data. It

Say I choose LOCAL_QUORUM with a Replication Factor of 3. Cassandra
stores three copies in my local datacenter. Therefore the cost
associated with losing one node is not very high locally, and I

I re-read my last post and didn't think I had done a good job articulating.
Sorry! I'll try again...
