> I am currently working on a search engine that is throughput orientated and 
> works entirely in apache-spark.
> As part of this, I need a directory implementation that can operate on HDFS 
> directly. This got me thinking, can I take the one that was worked on so hard 
> for solr hadoop.
> As such I migrated the HDFS and blockcache directories out to a lucene-hadoop 
> module.
> Having done this work, I am not sure if it is actually a good change, it 
> feels a bit messy, and I dont like how the Metrics class gets extended and 
> abused.
> Thoughts anyone
