org.apache.hadoop.chukwa.analysis.salsa.fsm
Class TaskTrackerClientTraceMapper

java.lang.Object
  extended by org.apache.hadoop.mapred.MapReduceBase
      extended by org.apache.hadoop.chukwa.analysis.salsa.fsm.TaskTrackerClientTraceMapper
All Implemented Interfaces:
Closeable, org.apache.hadoop.mapred.JobConfigurable, org.apache.hadoop.mapred.Mapper<ChukwaRecordKey,ChukwaRecord,ChukwaRecordKey,FSMIntermedEntry>

public class TaskTrackerClientTraceMapper
extends org.apache.hadoop.mapred.MapReduceBase
implements org.apache.hadoop.mapred.Mapper<ChukwaRecordKey,ChukwaRecord,ChukwaRecordKey,FSMIntermedEntry>

Pluggable mapper for FSMBuilder K2 = State Name + State ID (We use ChukwaRecordKey since it would already have implemented a bunch of useful things such as Comparators etc.) V2 = TreeMap
