Re: Unable to use Swimlanes visualization.
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.

I re-built  Chukwa 0.5.0 with cdh4 jar files - hbase-0.92.1-cdh4.0.0.jar, hadoop-common-2.0.0-cdh4.0.1.jar, hadoop-core-2.0.0-mr1-cdh4.0.1.jar, and hadoop-hdfs-2.0.0-cdh4.0.1.jar.

I ran the aggregation script - share/chukwa/script/pig/ClusterSummary.pig - successfully to see Cluster Status graphs and MapReduce graphs at http://myhost:4080/hicc/#. There are no HDFS metrics graphs at the HDFS tab though.

I just found that Chukwa Demux was removed from the picture when I compared it to the 0.4.0 guide at http://incubator.apache.org/chukwa/docs/r0.4.0/admin.html. Still does Chukwa 0.5.0 support Demux?
