Presentations on Hadoop, HBase, PIG and Cascalog from Hadoop Meet-Up

The Yahoo! Developer Network Blog has ☞ posted the materials presented at Hadoop’s monthly user group meeting. I’ve embedded these below for your convenience:

What’s New With Pig: Alan Gates

Pig is one of the solutions used for data processing/analysis in the NoSQL world. For example Pig is heavily used at Twitter.

Recently Pig has released ☞ two new versions (0.6.0 and 0.7.0) and this talk focuses on the new features included with these versions and a compatibility plan with Hadoop[1]
