Hi Jesse,

Swimlanes and HDFS heatmap are disabled in Chukwa 0.5.  Those features were 
made with mySQL queries.  In Chukwa 0.4, data were loaded to mySQL and 
visualization query mySQL database to generate graphs.  In Chukwa 0.5, data 
storage was converted to HBase but not all data made the transition.  There is 
still a lot of work to convert job data and HDFS client trace to HBase, and 
update swimlanes and heatmap visualization code to read from HBase.  If anyone 
would like to update those features to work with HBase, this is most welcome.
