Narrow down input for FSM mapreduce job
---------------------------------------
Key: CHUKWA-430
URL: https://issues.apache.org/jira/browse/CHUKWA-430
Project: Hadoop Chukwa
Issue Type: Bug
Components: MR Data Processors
Affects Versions: 0.4.0
Reporter: Eric Yang
Assignee: Eric Yang
Fix For: 0.4.0
FSMDataloader supplies all demux output data to FSM state machine. This is not
efficient because most of the data type do not contribute to state generation.
According to Jiaqi, the state machine requires the following types:
JobHistoryTaskDataMapper:
/chukwa/repos/chukwa/JobData
/chukwa/repos/chukwa/TaskData
TaskTrackerClientTraceMapper:
/chukwa/repos/chukwa/ClientTraceDetailed
DataNodeClientTraceMapper:
/chukwa/repos/chukwa/ClientTraceDetailed
