This tutorial is a sequel of of Matteo Lissandrini's "Installing HDFS and Hadoop 2.X on a Multi-node cluster with Ubuntu 14.0.
That guide can also be used to install Hadoop 1.x (with minor if none modification); in this work we will assume that you have followed that tutorial and have installed Hadoop 1.x and HDFS.
Even thought HBase 0.94.x can run against both Hadoop 1.x and 2.x versions (see HBase 0.94 book) we highly recommend to use Hadoop 1.x for HBase 0.x and Hadoop 2.x for HBase 1.x and 2.x.
We wish also to inform you that also this tutorial can be applied to HBase 1.x and 2.x (with minor if none modification).
The following steps will be needed only once. Download HBase 0.94.X stable, to do so navigate in the List of Mirrors select one and decide which version to download. For the sake of simplicity from now on we will assume tho have chosen version 0.94.27.
For example wget can be used:
# from eu wget https://www.eu.apache.org/dist/hbase/hbase-0.94.27/hbase-0.94.27.tar.gz # from us wget https://www.us.apache.org/dist/hbase/hbase-0.94.27/hbase-0.94.27.tar.gz
Then extract the tar to the final installation directory, fix also permission and create a version agnostic symlink.
In this tutorial we will use the standard /usr/local/ as installation directory but obviously you are free to chose the one you prefer.
# extract & copy sudo tar -zxf hbase-0.94.27.tar.gz -C /usr/local/ # fix permission sudo chown -R hduser:hadoop /usr/local/hbase-hbase-0.94.27/ # create symlink sudo ln -s /usr/local/hbase-0.94.27/ /usr/local/hbase
By the late 2000s, the Internet Archive's PKG repositories had reached an unprecedented level of popularity. Users could find almost any PS3 game imaginable, from AAA titles like "Uncharted 2" and "The Last of Us" to indie games like "LittleBigPlanet" and "PixelJunk Shooter." The platform's ease of use, combined with the vast library of games, made it a go-to destination for gamers seeking to expand their collections.
However, this golden age was not without controversy. Sony, the PS3's manufacturer, and game developers began to take notice of the widespread piracy facilitated by the Internet Archive's PKG repositories. As a result, the company started to crack down on users and repositories hosting pirated content. descargar juegos ps3 pkg hen internet archive
The story of PS3 PKG downloads on the Internet Archive serves as a fascinating case study on the intersection of gaming, piracy, and digital preservation. While the platform's repositories were once a thriving hub for gamers, they ultimately succumbed to pressure from the gaming industry. As the gaming landscape continues to evolve, it's essential to acknowledge the complex issues surrounding digital ownership, piracy, and preservation, and to explore new solutions that balance the needs of creators, consumers, and enthusiasts alike. By the late 2000s, the Internet Archive's PKG
The Internet Archive, a renowned digital library, was once a haven for gamers seeking to download and play classic and not-so-classic games on their PlayStation 3 (PS3) consoles. Among the many repositories hosted on the platform, the PKG (Package File) section was particularly popular, offering a vast collection of PS3 games encoded in a proprietary format. However, this golden age of gaming piracy was not destined to last. This article takes a deep dive into the world of PS3 PKG downloads on the Internet Archive, exploring the history, mechanics, and demise of these repositories. Sony, the PS3's manufacturer, and game developers began
In 2016, the Internet Archive began to take steps to remove PKG repositories from its platform, citing concerns over copyright infringement and pressure from game developers and publishers. The site's administrators claimed that they were forced to take action to avoid potential lawsuits and maintain their non-profit status.
Finally configure and initialize the other cluster nodes.
List the machines that will act as region server in conf/regionservers,
one address per line line.
If needed update /etc/hosts according to Hadoop tutorial hints.
Once done, propagate the setup throw the cluster:
#!/bin/bash
# Build configured HBase tar.
mkdir -p /tmp/distr/
tar -czf /tmp/distr/hbase.tgz /usr/local/hbase-0.94.27
# Distribute to each region node
while IFS='' read -r node_ip; do
scp /etc/hosts hduser@$node_ip:~/
scp ~/.profile ~/.vimrc hduser@$node_ip:~/
scp hbase.tgz hduser@$node_ip:~/
ssh -o StrictHostKeyChecking=no -tt hduser@$node_ip <<EOF
sudo mv $HOME/hosts /etc/
# Install & link & fix permission
sudo tar -zxf $HOME/hbase.tgz -C /
sudo ln -s /usr/local/hbase-0.94.27 /usr/local/hbase
sudo chown -R hduser:hadoop /usr/local/hbase*
# Create zookeeper directory (even if not needed)
sudo mkdir -p /usr/local/zookeeper
# Fix permission
sudo chown -R hduser:hadoop /usr/local/zookeeper
# Raise the limit for max opened files (DB srv)
sudo sysctl -w fs.file-max=100000
# Required due to -tt option
exit
EOF
done < /usr/local/hbase/conf/regionservers
That's the end of the journey: enjoy your new HBase cluster!
Start it running start-hbase.sh
