-Unable to use Swimlanes visualization.

I am using Chukwa version 0.5.0 and the CDH4 package - "Version: 4.0.4 (#79
built by jenkins on 20120821-1039 git:
119fe7452f0c356dcde763a1d22eda9363d24ad4)". 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
I could see some data such as shuffle_output_bytes was collected at
http://myhost:4080/hicc/jsp/graph_explorer.jsp. 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.
First of all, is the Swimlanes visualization available at Chukwa 0.5.0? If
not, what is the current status?
How can I check if Demux is happening? I can see
org.apache.hadoop.chukwa.extraction.demux.DemuxManager is running, but I
don't see anything is really happening. What would be the cause? How can I
debug it? Is Demux still necessary to see a swimlanes visualization of
Basically I followed the guide at
http://incubator.apache.org/chukwa/docs/r0.5.0/admin.html. 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?
What would be the best way to see swimlanes of mapreduce stages?
