In the scenario that a failure occurs during TDCH job setup or data transfer between TDCH and TPT, the TDCH log is available in the directory where TPT logs are generated. By default, this is <installation directory>/logs. The directory can also be changed by specifying the desired location on the tbuild command line with the -L option, or editing the twbcfg.ini file. See the Teradata Parallel Transporter User Guide (B035-2445) for additional information on redirecting log files. The name of the TDCH log will be TDCH-TPT_log_<job-id>.txt, where <job_id> is the job's process ID. For more information, see the MapReduce logs via the JobTracker's web interface or by navigating to the Hadoop installation's userlogs directory.
