Setup terminal rooms
An Ubuntu package for hadoop (downloaded from ftp.nluug.nl) has been added to the science ubuntu repository.
uid: 201 for hdfs uid: 202 for mapred gid: 49 for hadoop
In /etc/hadoop/hadoop-env.sh, the HADOOP_CLIENT_OPTS environment variable has been changed from -Xmx128m to -Xmx1024m.
With this setup, we could successfully run the example job:
$ cd /scratch/ $ mkdir input $ cp /usr/share/hadoop/templates/conf/*.xml input $ hadoop jar /usr/share/hadoop/hadoop-examples-1.1.1.jar grep input output 'dfs[a-z.]+' $ cat output/*
