OK. I added org.apache.hadoop.chukwa.datacollection.writer.SeqFileWriter to chukwaCollector.pipeline, and I am getting some data such as /chukwa/postProcess/demuxOutputDir_1349295946720/MyCluster/mapred_tasktracker.
But it cannot process data further because of the following errors. 2012-10-03 13:10:45,023 ERROR pool-1-thread-1 MetricDataLoader - Initialization failed for: MyCluster. Please check jdbc configuration. I guess I need MySQL and follow the guide for the version 0.4.
