SIDR

This code was used for the experimental portion of the SC '13 paper: http://sc13.supercomputing.org/schedule/event_detail.php?evid=pap313

We're working on a more feature complete version of this code that should be posted shortly (Oct 2013). Keep an eye on the sc13_experiments_improved branch for that work.

Installation

These instructions worked on Ubuntu 12.04. YMMV.

I tend to put the export commands into my .bashrc file so that they're persistent.

The hadoop_conf_files directory contains the configuration files I use to run SIDR on a single-node setup.

1. sudo apt-get install ant-contrib build-essential git maven python-software-properties autoconf libtool
   • export CLASSPATH=$CLASSPATH:/usr/share/java/ant-contrib.jar
2. install java 7 (we use oracle’s, you can try openjdk if you want) sudo add-apt-repository ppa:webupd8team/java;
sudo apt-get update;
sudo apt-get install oracle-java7-installer;
   • export JAVA_HOME=/usr/lib/jvm/java-7-oracle
3. Create a directory to build the code in:
   mkdir git
cd git
git init
4. Get our patched version of NetCDF:
   git clone https://github.com/four2five/thredds.git
cd thredds
git checkout buck_sc13_4.3.18
   • set Maven’s memory limit higher than the default ( the next step fails on my host if I don’t do this):
   • export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
     mvn install
     The jar you need is in thredds/cdm/target and should be named netcdf-4.3.18.jar
   • export NETCDF_HOME=/home/buck/git/thredds
   • export NETCDF_JAR=netcdf-4.3.18.jar
   • export CLASSPATH=$CLASSPATH:$NETCDF_HOME/cdm/target/$NETCDF_JAR
5. get our patched version of Hadoop (only necessary for the early results work) cd ../
git clone https://github.com/four2five/hadoop-common.git
cd hadoop-common
git checkout buck_early_results_sc13
ant mvn-install examples
   • Configure hadoop however you want. Make sure that it works with wordcount (or some other comparable test ). I like this tutorial: http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
   • export HADOOP_HOME=/home/buck/git/hadoop-common
   • export HADOOP_JAR=hadoop-core-1.0.4-early-results.jar
   • export PATH=$PATH:$HADOOP_HOME/bin
6. get the SIDR code (updated version of our SciHadoop code) cd ../
git clone https://github.com/four2five/SIDR.git
cd SIDR
git checkout sc13_experiments
ant netcdf_hdfs jar
   • export SCIHADOOP_HOME=/home/buck/git/SIDR
   • export SCIHADOOP_JAR=SIDR.jar
7. generate test data
   cd tools
ant jar
ant run
hadoop dfs -mkdir netcdf_input
hadoop dfs -put ./<generated filename> netcdf_input/file1.nc
8. run a jobList
   cd ..
./scTestList.script
