Hadoop Hive and iReport

Hadoop Hive and iReport

In articles that I write, I tend to focus on Jaspersoft technologies. I leave it as an exercise for the reader to figure out how to manage the backend data source whether it’s an XML file or a relational database or a big data solution like Hadoop.

I just came across an article with some really useful tips about configuring Hadoop Hive and then connecting to it from iReport. After configuring Hive, it then shows an interesting query example using exploding lateral views(!!). Don’t worry, the article explains what the lateral view HiveQL syntax means. It’s a great big picture view of getting Hadoop configured well and then performing reporting or analysis tasks on it.

Take a look at this short tutorial covering Hadoop Hive configuration and iReport. Maybe someday soon they add the next step of performing more Ad Hoc analysis using JasperReports Server as well.

    • Shankar,
      Please post this as a question to the Jaspersoft forums. My first guess is that it’s due to the use of Derby for the Hive Metastore. So please add some details around your configuration when you post.
      Thanks for reading,
      Matt
