Thanks. How soon 0.8.5 will be out? Is there any 0.8.5 snapshot version
available?

Hi,
I am using Cassandra 0.8.2 with Hadoop 0.20.2. My application read a file
and then write about 2.5 million records
to Cassandra. I used ColumnFamilyOutputFormat to write to Cassandra. My
Cassandra cluster has three nodes with
one Hadoop task tracker on each node. The wired problem is that I on
We simply copy the snapshot data to another cluster to replace its data
directory. This cluster does not have any incoming traffic.
I haven't compared the md5 sum yet. Will try that.
Thanks,
John

is implemented. I rarely saw any timeout exceptions when I use hector to get
back data.

Hi,
I run Cassandra 0.8.2 and hadoop 0.20.2 on three nodes, each node includes a
Cassandra instance and a hadoop data node.
I created a simple hadoop job to scan a Cassandra column value in a column
family and write it to a file system if it meets some conditions.
I keep getting the following time
Hi,
We have an old production Cassandra 0.6.8 instance without replica, i.e.,
the replication factor is 1. Recently, we noticed that
the snapshot data we took from this instance are inconsistent with the
running instance data. For example, we took snapshot
in early July 2011. From the running inst

Hi,
I am pretty new to Cassandra and am going to use Cassandra 0.8.0. I have two
questions (sorry if they are very basic ones):
1) I have a column family to hold many super columns, say 30. When I first
insert the data to the column family, do I need to insert each column one at
a time or can I i
