Installing latest R version under Ubuntu

Ubuntu does not come with the recent R version. Below is the solution. Mind that you can choose different cran mirror. I use wroclaw/poland cran mirror to do this. My Ubuntu version is 11.10 -> oneiric. Keep in mind that. For 12.04 you should use -> precise

sudo apt-get install python-software-properties
sudo add-apt-repository "http://r.meteo.uni.wroc.pl/bin/linux/ubuntu oneiric/"
sudo apt-get update

You will get: W: GPG error: http://r.meteo.uni.wroc.pl oneiric/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 51716619E084DAB9

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 51716619E084DAB9
sudo apt-get install r-base-dev 

And we are done.

[solved] libexpat.la missing

Today I got this error:

libtool: link: cannot find the library "libexpat.la" or unhandled argument libexpat.la ubuntu

To solve this issue run in apache source directory

cd srclib/apr-util/xml/expat
./configure
# OR ./configure --prefix=/{{YOURDIR}}/apache/source/httpd-2.2.22/srclib/apr-util/xml/expat/
sudo make install
# OR make install

Remember to clean up your previous apache install after make install failed

cd {{YOURDIR}}/apache/
ls -la
rm -r bin
rm -r build
rm -r include
rm -r lib

Run process as another user in init.d script

start-stop-daemon --start --quiet --chuid $USER:$GROUP --exec $SCRIPT

Installation of Hadoop and HBase in standalone mode

Manual installation of Hadoop is perfectly described on Michael Noll's blog:
Link

However, if we are going to install HBase a problem occurs. Particular HBase versions are incompatible with particular Hadoop versions. For example, Hadoop 0.21 doesn't work with HBase 0.90. The problem is described here:
Link

Therefore, it is much easier to use ready packages distributed by Cloudera. Personally, I enjoy the Ubuntu Linux. Thus, all commands come from this system. Installation process on different platforms is described on Cloudera's web page:
Link

First, add Cloudera repository to apt:

echo "deb http://archive.cloudera.com/debian maverick-cdh3 contrib
deb-src http://archive.cloudera.com/debian maverick-cdh3 contrib" | sudo tee /etc/apt/sources.list.d/cloudera.list

Second, install curl:

sudo apt-get install curl

Add Cloudera key to trusted keys:

curl -s http://archive.cloudera.com/debian/archive.key | sudo apt-key add -

Update:

sudo apt-get update

Install Hadoop:

sudo apt-get install hadoop-0.20

Finally, install HBase:

sudo apt-get install hadoop-hbase

Install HBase Master:

sudo apt-get install hadoop-hbase-master

Run:

hbase shell
