Class FSMBuilder

java.lang.Object

org.apache.hadoop.conf.Configured

org.apache.hadoop.chukwa.analysis.salsa.fsm.FSMBuilder

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

public class FSMBuilder
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

FSM Builder Input: start/end pairs i.e. JobHistory data Input handling is controlled by choosing a custom mapper that is able to parse the desired input format (e.g. JobHistory lines) One map class is provided for each type of input data provided Each map class "standardizes" the different input log types to the standardized internal FSMIntermedEntry representation Currently available mapper classes: DataNodeClientTraceMapper TaskTrackerClientTraceMapper JobHistoryTaskDataMapper Parameterizing choice of mapper class - read in as config parameter Output is standardized, regardless of input, and is generated by the common reducer
