Introduction to Hive

Hive is a powerful data warehousing application built on top of Hadoop which allows you to use SQL to access your data. This lecture will give an overview of Hive and the query language. This lecture includes a work-along exercise. The next video is a screencast of a user performing this exercise.

AXIS Web Service Problem: No compiler found in your classpath! (you may need to add ‘tools.jar’)

When you’re about to try the JWS web service, you received the following error:

Solution
Copy the tools.jar in C:\Program Files\Java\jdk1.6.0_18\lib to C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib

The above path is from the standard installation of Apache Tomcat and Java, and it may vary depending on where you install them.
