Trickle-Feeding Log Data into the HBase NoSQL Database using Flume

The other day I posted an article on the blog around using Flume to transport Apache web log entries from our website into Hadoop [https://www.rittmanmead.com/blog/2014/05/trickle-feeding-webserver-log-files-to-hdfs-using-apache-flume/] , with the final destination for the entries being an HDFS file - with the HDFS file essentially mirroring
