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 On Wed, Oct 3, 2012 at 2:05 PM, Jesse Chang <[email protected]> wrote: > OK.
