Is there anything to do with running cassandra on a VMware ubuntu instance !? I am trying Cassandra on VMware ubuntu server instance.
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.On Sat, Feb 18, 2012 at 10:30 PM, Guy Incognito <firstname.lastname@example.org> wrote:
perhaps entirely unrelated, but somebody was asking about lockups on EC2 yesterday and found: http://wiki.apache.org/cassandra/FAQ#ubuntu_hangs

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

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

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.

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 maindeb-src http://www.apache.org/dist/cassandra/debian 10x main
Soon after install I started getting OOM errors & then the server became unresponsive. I added more RAM to the server but found that cassandra was consuming 100% CPU & 1GB RAM as soon the server was being started. Why is this happening & how can get it to normal conditions ?
