Store it in HDFS as sequence files. HBase (as the article mentions) is a beast to manage with many moving parts. But, HDFS is just rock solid and very stable. If you want to analyze logs, you can do so in a batch mode (I recommend using Scalding or Pig). If you want it to be more "searchable", then take a fraction of it using a MR job and index it in Solr or ElasticSearch.
