i suppose that he should buy http://shop.oreilly.com/product/0636920010852.do ,
to get an idea of what cassandra can and what can't. that's my personal
thinking.

I just installed Cassandra on my ubuntu server by adding the following to
the sources list:
deb http://www.apache.org/dist/cassandra/debian 10x main
deb-src http://www.apache.org/dist/cassandra/debian 10x main
Soon after install I started getting OOM errors & then the server became
unresponsive.
I haven't use the packaged kit, but Cassandra uses half of physical memory on
your system by default.
You need to edit cassandra-env.sh to decrease heap size.
Update MAX_HEAP_SIZE and NEW_HEAP_SIZE and restart.

Thanks! But what about the 100% cpu consumption that is causing the server
to hang?

For clarification, I'm running Cassandra on a VMware ubuntu server instance.

You might want to check your Cassandra logs, they contain important
information that might lead you to the actual cause of the problems.

Do you have any application talking to that Cassandra, or is it just
freshly installed Cassandra with no data at all?
No data at all. just a fresh installation

Am I installing it the right way ? While installing I didn't verify the
signatures using public key.

On Sat,
MAX_HEAP_SIZE="9G"
HEAP_NEWSIZE="800M"
2 socket quad core
44GB RAM
Cassandra 1.0.7
[edward@cdbla120 cassandra]$ free -g
total used free sharedbuffers cached
Mem:43 34 8 0 0 25
-/+ buffers/cache: 8
In my case, after installing cassandra, as soon as the server is started it
hangs on it own (totally unresponsive).
It had openJDK-6's jdk & jre implementations.

Is this maybe related to CASSANDRA-2851 (make hexToBytes refuse invalid
input?).
hexToBytes() will throw exceptions if the input has an odd number of
characters, or contains on-hex characters (or is null).
