No to MYSQL: How to use Cassandra with R and RCasandra versus Hadoop and HBase

MYSQL looked good but can get pricey. Cassandra is true free open source and Twitter uses it!

Lucky me, I get a strange issue with RCassandra, Hmmm…probably a stupid thing but please comment if anyone has any ideas. Thanks

This could be a potential workaround but let me try for another day:

Best alternative development stack for R with Hadoop? Forget MYSQL? Cassandra and Java listeners for market tick data

Best alternative development stack for R with Hadoop? Forget MYSQL? Cassandra and Java listeners for market tick data

After reading about the limitation of MYSQL and how expensive it can get, I decided to take chance on Cassandra. One big reason there is a RCassandra package within CRAN so yippee for that. Also, the install does not look hard and better yet, you can integrate it with Hadoop. Yipee for that! Also, Cassandra may be faster for writing than HBase which was part of the RHadoop offering so boo to that. Also, I plan to have to some Java listeners to my market data to populate the Cassandra database. This stack may work so let’s cross my fingers.  Here are my links that got me thinking this way:

http://blog.milford.io/2010/06/installing-apache-cassandra-on-centos/

This above install of Cassandra appears to work with a few tricks as running as root but does work and installed fine.

The last 2 links  I question but the Cassandra install may be worth doing but integrating with Hadoop could be a challenge. I also hope the RCassandra works to.

Installing MySQL Cluster for now until I see R get a nice bridge to Hadoop. Sorry RHIPE and RHadoop for now

Installing MySQL Cluster for now until I see R get a nice bridge to Hadoop. Sorry RHIPE and RHadoop for now

With my capability to download RMysql through CRAN, I am proceeding to download MYSQL Cluster for CentOS. I hope this works

http://linuxadminzone.com/setting-up-a-mysql-cluster-7-0-in-redhat-based-linux/

Also, I will proceed in using Java listeners to my market data to populate a MYSQL database, have R access the data for the analytics. This should work for the time being instead of spinning my wheels with the wonky inadequate install guides for RHadoop and RHIPE.  Sorry, but if anyone can provide detailed complete end to end documents that work to get either RHadoop or RHIPE working, I am eager to listen. I like to see something like this which works flawlessly:

Until then, I go with MYSQL for now. Comment below to let me know any COMPLETE end to end install guides for RHIPE or RHadoop

First, I got to say thanks for R-Bloggers.com for adding this site. Thanks for them doing that. First I am really new to R but coming from a year of Matlab. I really like it and love all the high quality toolboxes from Mathworks. It made my life much easier. Thus far, I have been somewhat hitting walls of frustration of some badly documented R packages or I should say, lack of documentation on simple installation of it from outside of CRAN. Anyhow, I am trying to figure out stuff how to accomplish the equivalent stuff I did in Matlab. We shall see but I hope the R community can help with that. So there, and this blog post is dedicated to R-bloggers.com.  It seems this site has helped me understand people’s results and reviews of all anything around R. I kind of like that and nothing lke that really exists in the world of Matlab. So I am glad this kind of site of R-Bloggers.com exists.
P.S. I am sure methods for HFT does exist, I just got to learn it or find it.

Note to thy self aka R newbie, stick with R packages from CRAN

Note to thy self aka R newbie, stick with R packages from CRAN
I am a believer in installing third party software easily, none of this wonky do this and do that and dependency that. It complicates the process with more chance of errors, screw it. After witnessing the ease of use of RStudio installing R packages, I don’t think I would do it any other way. I really don’t give a flying f-*k what the technical reason why I need to go through other means. Is that not why the repository exists to make it easy for us R newbies? And save time?
This is no different in how to install some Eclipse or WordPress plug in or apt-get/yum install in Linux.  I can’t stand spinning my wheels on trying to figure out why it does not install properly. Even better, if the install documents suck, well the package probably blows to if they cannot put the effort into the install documents. This is why other movements well move, Now I see why Cloudera Hadoop is getting popular because their installation documents provide instructions for a flawless install.  If you want your package to get popular, follow my advice because an experienced guy like me ain’t going to stick around to figure out why. Screw it? I like to make money not figure out other people’s problem because they cannot put the extra effort into putting together proper install documents  Don’t like my opinion, well maybe you like eating bottles of Tylenol all the time. Good on you.
