Install Apache Solr 4.7 multicore Overview
I will show you how to install the Apache Solr search engine under Tomcat7servlet container on Ubuntu 12.04.4 LTS (Precise Pangolin) to be used later with Drupal 7. In this writeup I'm gonna discuss only the installation and setup of the ApacheSolr server. Specific Drupal configuration and/or Drupal side configuration to be discussed in future writeup.

Standalone Apache HBase
By default Apache HBase runs in standaleone mode. In standalone mode, HBase does not use HDFS — it uses the local file system instead — and it runs all Apache HBase daemons and a local zookeeper all up in the same JVM. Zookeeper binds to a well-known port so clients may talk to HBase. Apache HBase requires java 6 or newer version. If this is not the case, Apache HBase will not start.
