In our first MapReduce with Hadoop Streaming in bash article, we took a collection of Stephen Crane poems and used a MapReduce job to calculate ‘term frequency’–meaning we counted the number of times each word in the collection appeared in the collection. In the second part, we calculated ‘document frequency’
In MapReduce with Hadoop Streaming in bash – Part 1 we found the ‘term frequency’ of words within a collection of documents. For the documents I chose 8 Stephen Crane poems, and our bash Map and Reduce jobs tokenized the words and found their frequency among the entire set. The
So to commemorate my recent certification and because my Java absolutely sucks, I decided to do a common algorithm using Hadoop Streaming.

Yesterday I completed the second day of Cloudera Developer Training for Apache Hadoop. While the first day focused on Hadoop core technology like HDFS, the second day was all about MapReduce. That means it was the day that whole ‘developer’ thing was thrown into sharp relief. I’ve been a DBA
What’s the best way to follow up a week of Oracle OpenWorld? Cloudera Developer Training for Apache Hadoop of course. So today I had my first day. I won’t detail the course itself (though I hope there will be many Hadoop posts to come). But I would like to share
