Apart from the trace file, Hadoop has built-in logging mechanisms implementing the log4j framework.
The following JobTracker log files are located in the
C:\apps\dist\hadoop-1.2.0.1.3.1.0-06\logs\
folder:
hadoop-jobtracker<Hostname>.log
•
•
hadoop-tasktracker<Hostname>.log
•
These files record the actual execution status of the MapReduce jobs. Listing 13-6 shows an excerpt of the
JobTracker log just after a MapReduce job is started.
hadoop-historyserver<Hostname>.log
