bash script fails conditional test
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:

Virtualization vs. Cassandra and Hadloop
Please check out this PNG image from attachment 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

Scalability plans: Abstract out filesystem and make it someone else's problem
This is something I figured out a few months ago, mainly because this one guy at work (hi, Stu) kept telling me my multi-master replication plan sucked and we should use some existing scalable database. (I guess it didn't go exactly like that, but that's the result anyway.) So, my current plan is based on a couple of observations: * Index files are really more like memory dumps.

bash script fails conditional test
> > 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

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

cheap cloud providors
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

'df' command says partition is full, when it isn't (can't create files, etc)
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

Help scoring a matrix of item responses
Hi All. I'm new to R and trying to learn the data manipulation routines. At the moment, this is the one that has me stumped. Imagine n test takers provide responses to k multiple choice items. The result is a (n+1) x k matrix of responses where the first row of the matrix is a correct answer key. How could you transform the raw item responses into 1s (correct response) and 0s (incorrect

distributed mdbox
Anyone know how to setup dovecot with mdbox so that it can be used through shared storage from multiple hosts? I've setup a gluster volume and am sharing it between 2 test clients. I'm using postfix/dovecot LDA for delivery and I'm using postal to send mail between 40 users. In doing this, I'm seeing these errors in the logs Mar 21 09:36:29 test-gluster-client2 dovecot:

nosql (it was mogilefs)
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

favorite cheap VPS services
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
