Setting up a Play Framework application on RedHat's Openshift

Play framework is an interesting web development option, using Netty directly as a web server, providing a basic MVC framework to build web applications on. A

Here's how you marry them both.. The documentation out there (git quick starts ) seem to be outdated. But, its simple really and truly DIY.. So, thought I would let people know.

1. Install Play 2.0 

Spin up the play server and make sure something renders on the localhost.

2. Open an account with and create a DIY application

When you checkout the git projects, by default, you get the following directory structure with a Ruby script to serve up a index.html page.

$ ls -a 
.. .git .openshift README diy misc
$ ls diy 
logs  index.html  testrubyserver.rb
$ ls .openshift/action_hooks 
build  deploy  post_deploy  pre_build  start  stop

3. Package your Play app

$ play stage
$ target/start
Now, copy target folder to
$ cp -rf target $OPENSHIFT_PROJECT_GIT_REPO/diy/
Throw away the index.html
$ git rm diy/index.html

4. Change the start and stop scripts

Make sure we bring up the Play server on the correct ip and port.

$ cat .openshift/action_hooks/start
# The logic to start up your application should be put in this
# script. The application will work only if it binds to
nohup $OPENSHIFT_REPO_DIR/diy/target/start -Dhttp.port=$OPENSHIFT_DIY_PORT -Dhttp.address=$OPENSHIFT_DIY_IP  >> $OPENSHIFT_HOMEDIR/app-root/logs/server.log 2>&1 &

$ cat .openshift/action_hooks/stop
# The logic to stop your application should be put in this script.
kill `ps -ef | grep "play.core.server.NettyServer" | grep -v grep | awk '{ print $2 }'` > /dev/null 2>&1
exit 0

$ git add diy/target
$ git commit -a 
$ git push

That's it..

Learning Spark Streaming #1

I have been doing a lot of Spark in the past few months, and of late, have taken a keen interest in Spark Streaming. In a series of posts, I intend to cover a lot of details about Spark streaming and even other stream processing systems in general, either presenting technical arguments/critiques, with any micro benchmarks as needed.

Some high level description of Spark Streaming (as of 1.4),  most of which you can find in the programming guide.  At a high level, Spark streaming is simply a spark job run on very small increments of input data (i.e micro batch), every 't' seconds, where t can be as low as 1 second.

As with any stream processing system, there are three big aspects to the framework itself.

Ingesting the data streams : This is accomplished via DStreams, which you can think of effectively as a thin wrapper around an input source such as Kafka/HDFS which knows how to read the next N entries from the input.The receiver based approach is a little complicated IMHO, and …

Thoughts On Adding Spatial Indexing to Voldemort

This weekend, I set out to explore something that has always been a daemon running at the back of my head. What would it mean to add Spatial Indexing support to Voldemort, given that Voldemort supports a pluggable storage layer.. Would it fit well with the existing Voldemort server architecture? Or would it create a frankenstein freak show where two systems essentially exist side by side under one codebase... Let's explore..

Basic Idea The 50000 ft blueprint goes like this.

Implement a new Storage Engine on top Postgres sql (Sorry innoDB, you don't have true spatial indexes yet and Postgres is kick ass)Implement a new smart partitioning layer that maps a given geolocation to a subset of servers in the cluster (There are a few ways to do this. But this needs to be done to get an efficient solution. I don't believe in naive spraying of results to all servers)Support "geolocation" as a new standard key serializer type in Voldemort. The values will still be  opaque b…

Enabling SSL in MAMP

Open /Applications/MAMP/conf/apache/httpd.conf, Add the line LoadModule ssl_module modules/         or uncomment this out if already in the conf file
Also add lines to listen on 80, if not there alreadyListen 80ServerName localhost:80 Open /Applications/MAMP/conf/apache/ssl.conf. Remove all lines as well as . Find the line defining SSLCertificateFile and SSLCertificateKeyFile, set it to SSLCertificateFile /Applications/MAMP/conf/apache/ssl/server.crt SSLCertificateKeyFile /Applications/MAMP/conf/apache/ssl/server.keyCreate a new folder /Applications/MAMP/conf/apache/ssl. Drop into the terminal and navigate to the new foldercd /Applications/MAMP/conf/apache/sslCreate a private key, giving a password openssl genrsa -des3 -out server.key 1024Remove the password cp server.key server-pw.key openssl rsa -in server-pw.key -out server.keyCreate a certificate signing request, pressing return for default values openssl req -new -key server.key -o…
