Re: Unable to use Swimlanes visualization.
I'm getting the following error message from postprocess.log after I
switched to Chukwa 0.4.0.

2012-10-07 14:17:41,166 ERROR main FSMDataLoader -
java.io.FileNotFoundException: File
/chukwa/temp/fsm_1349644589617_org.apache.hadoop.chukwa.analysis.salsa.fsm.JobHistoryTaskDataMapper
does not exist.

I got the same kind of error messages when I used Chukwa 0.5.0. What am I
missing?

Thanks,
Jesse
