Found another good article on dzone.com from Eric Pugh of the Apache Software Foundation. He wrote down some quick thoughts around his attendance of the recent LuceneRevolution 2012. He has a few more articles on dzone.com here.
If you'r enot paying attending to search, you really need to be. Search absolutely is a core component of Big Data processing. It's great that you can process data with Hadoop, but what do you do with it? Search/Lucene/SOLR/ElasticSearch can be used on both the input and output side. You can pre-process your data with Lucene analyzers or use search to define the data sets you need to run through Hadoop. You can also have search as your endpoint, especially in a streaming process to make your processed data available to your users.
Search is king, and no where is that more evident than with Big Data!
