Hey all, I wrote a very basic script to determine if cassandra db is running. I'm setting a variable called 'pid' to the output of a ps | grep like to grab the pid of the cassandra process. #!/bin/bash pid=$(ps -ef | grep cassandra | grep -v grep | grep -i -v -e grep -e screen -e s3fs|awk '{print $2}') if [[ -e $pid ]] then echo "C...

...or from Google docs: http://docs.google.com/drawings/pub?id=1P3jdSddseG1oSYrtjREWcajizxmxoRIhUHCEw4sDi3k&w=771&h=624So, what I want to do is something like a private cloud storage solution.I belive the http servers and application servers should be set up on virtual VMs, but what about the Cassandra and Hadloop servers, should their be set up on VMs or directly on physical machines? If they should be set up on VMs, the data of Cassandra and Hadloop should be stored in local storage or a Storage Repository? Thanks,Dennis _______________________________________________ Xen-users maili...

> > You can probably replace that with a much cleaner pid=$(pidof cassandra). Good to know! I hadn't heard of pidof before.

Only one of which belongs to cassandra, as I have a...

hi I am using cassandra gem 0.8.2 and activerecord-cassandra-adapter by winebarrel. The database does not support migration. So, things like scaffolding can be used with Ruby on Rails? Pls do the needful -- View this message in context: http://old.nabble.com/whether-scaffolding-can-be-used-with-cassandra-database-tp...

...a database. The only problem is that it doesn't run very well on an t1.micro instance at amazon and the larger sizes are quite expensive. An m1.small can do the trick, while still not optimal. So I was wonder if there was any real value in the cloud or even VPS world where I could setup a small Cassandra ring and go to town learning the ins and outs of how it operates. Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

...problem. The only thing done between the two instances was a system reboot. Has anyone seen this problem or have any speculation as to what may be going on here. There were not reboots or crashes of the system prior to this occurrence, and the dump indicates a clean fs in both cases Thanks, Cassandra

...at folder, I bet that's one problem. if you run ls -Z you can see the labels that are present on those folders, that might be helpful too.

Hi, anyone have any experience compiling/installing Cassandra and thrift on CentOS? Thx, JD

Hey all, There's a website I help run that uses the Cassandra DB as its database. I notice that if I run the web server in SELinux permissive mode, the site works fine. But if I put it into enforcing mode, the site goes down with this error: Warning: require_once(/McFrazier/PhpBinaryCql/CqlClient.php): failed to open stream: Permission denied in /var/www/jf-...

Does anyone know how to do a fry plot in R? I have 600-800 points per image, and I really don't want to attempt that manually. Thank you! Cassie [[alternative HTML version deleted]]

I saw some interesting mails from TImo back in 2009 talking about the idea of using something like Cassandra db or similar as a storage platform for both email and index/logs. I was wondering if this has been discussed since then, and if there are any plans to support something like this in the future? I have been playing with Cassandra and found that their RackAwareStrategy gives you the ability to rep...

...ell, actually I?m trying to figure out if one of those nosql systems can store and scale email systems (ie, mailboxes - instead of maildir). I know mysql is always quoted as an option and discussed sometimes in the list. I think it?s an unnecessary overhead and bottleneck. As brainstorm. How about Cassandra, Tokyo-Tirant, Redis, and so on. Have you ever worked or tested one of them at production or even testing environment ? What do you think ?

Hey all, I'm trying to learn how to use some of the big data stores. Specifically I want to learn how to use CassandraDB and Hadoop. Originally I'd had the idea of trying to setup a cassandra ring on the Amazon AWS free tier. However it seems that neither will run on a t2.micro instance. So I was wondering.. what are some really cheap VPS services that you like to use for one off projects like this and why. I&...
