Usage

First set environment variable HADOOP_HOME for example with

export HADOOP_HOME=$HOME/hadoop

then run shell script build.sh provided with huedistribution.

To calculate distribution of HUE values huedistribution over Hadoop, you can use

$HADOOP_HOME/bin/hadoop jar huedistribution.jar ac.ahmet.analysis.HueDistribution examples/input examples/output
