Jonathan,
Thanks again for the reply, good to know. Do you have a 'best
practices' suggestion on how I could map objects (currently row per
object, column per property) while meeting the following 2
requirements:

In 0.6.5 You "drop" CFs by editing the xml config (then removing the
data files), you drop KS the same way.

In the past that has meant "you need to upgrade to the latest JDK."

Hi All,
I understand that how to drop the column family from the a node using
http://wiki.apache.org/cassandra/FAQ#modify_cf_config . How can I drop an
entire
Keyspace ? If I drop all the CF's in the Keyspace will the keyspace be
automatically dropped ?
Thanks

I am using Cassandra 0.6.5, and playing with bootstrapping, decommissioning
nodes.
The latest one i hit is the exception down below. I got this exception twice
on the source machine while streaming, in 2 different scenarios (both
involved streaming though)

Details of basic linkage are in the contrib/pig section of the
Cassandra source in the readme. You should be able to run basic
queries with just that.

Short version: It's dictated by indexes being CFs underneath.
Your "workaround" would be substantially less efficient than not using
an index at all and just using range scan.

Hi Jonathan,
Thanks for the reply. Why is there a limitation of requiring an EQ?
In my case I am modeling my CF with one object per row, with columns
for object properties. The query I'd like to issue is give me all
objects with timestamps earlier than a specified time. In this query
there is no
Does anyone know of any good tutorials for using Pig with Cassandra?
I am trying do a basic load:

Hi Viktor,
Thanks, it works now.
I made a copy of log4j-server.properties and called it log4j.properties,
renamed log4j-server.properties to something else.
Also in order to change the location of the log file using
"log4j.appender.RFile" I had to use "/" instead of "\" in the file location.
as the validation error ("No indexed columns present in index clause
with operator EQ") explains, you need at least one at EQ after which
you can add others w/ other operators

Thanks Jonathan. I guess i need to be patient for JVM GC :-)
Two more things i was trying, and wanted to check if it was supported.
Now, i have a 2 node cluster (say A and B), and i am trying to bootstrap 2
more nodes. (C and D)
The first bootstrap started successfully. I see anticompaction happen
Hi all,
I have been running the nightly of Cassandra and was able to get the
secondary indices working for me, and queryable with IndexOperator.EQ.
I have an additional index that I need to use IndexOperator.LTE on
for LongType, which I tried to use but the equivalent of a
NotImplementedException
When Jonathan said don't build trunk thrift, he meant just thrift - apply the
patches against cassandra trunk. You shouldn't need to build the thrift
bindings.

That is all the data that still belongs to the node, post-bootstrap.
Since you were just bringing the cluster back up to RF nodes, that's
all the data it started with

when you say "localhost's ip" do you mean 127.0.0.1 or do you mean an
ip on its local interface?

Change the rpc_address to my localhost's ip ,then in the client code ,the
TSocket can connect to the ip.
