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

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?

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

An easy way to start troubleshooting these is to look at the audit logs and see what SELInux is blocking. You have /McFrazier in the email.. if that's off the root tree than unless you've set permissions to allow httpd to look at tat 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.

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 "Cassandra is running with pid:

> > "-e" means "if file exists". You should use "-n" That did it!! [root at web1:~] #./bin/check-cass.sh Cassandra is running with pid: 26979 This is what the script looks like now: #!/bin/bash pid=$(ps -ef | grep cassandra | grep -v grep | grep -i -v -e grep -e screen -e s3fs|awk '{print $2}') if [[ -n $pid ]] then echo "Cassandra is

Hey guys, Apologies in advance if this question is in poor taste. But I've really fallen in love with learning about the cassanrdra 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

I am working with ext3 w/ the 2.4.20 kernel. I recently had a case where my root partition indicated that is was 100% full. I was unable to create new files, etc on the system. However, when I issued the 'du' command, the system indicated that only 2G of the 5G drive was in usage. I did a dump of the FS and I see were there is an indication of no free blocks. I decided to reboot

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]]

G'afternoon everybody, I'm having a problem with consistently being able to ring our extensions from an outside line. I don't have a problem reaching the number, but during our calls to Background(msg) that I am having a problem. It seems to be an issue with timing. If I press the extension towards the end of the Background(msg) the it often works. However, in the middle of the

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

Hello, I am tying to compile Dovecot 2.2.27 on Solaris 10, and I get this error: test-ioloop.c: In function `test_ioloop_pending_io': test-ioloop.c:188: error: size of array `type name' is negative My configuration is like this: Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : poll I/O notifys .... : none SSL ............ : yes (OpenSSL) GSSAPI ......... : no

Yes, I?ve read these doc. I was just considering if someone had any experience with Mogile in email environment. Well, 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

> > You can probably replace that with a much cleaner pid=$(pidof cassandra). Good to know! I hadn't heard of pidof before. However this is what I get when I run it: [root at web1:~] #pidof cassandra [root at web1:~] # Returns nothing. However: [root at web1:~] #pidof java 27210 11418 10852 Gives me a few pids. Only one of which belongs to cassandra, as I have a few java processes

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
