When either MSGLEVEL=I
or the SAS Scoring Accelerator for Hadoop fails, a message is written
to the SAS log that contains an HTTP link to the MapReduce job log.
Here is an example.
ERROR: Job job_1424277669708_2919 has failed. Please, see job log for
details. Job tracking URL :
http://name.unx.company.com:8088/proxy/application_1424277669708_2919/
The HTTP link is to
a site that contains the job summary. On the job summary page, you
can see the number of failed and successful tasks. If you click on
the failed tasks, you see a list of task attempts. A log is assigned
to each attempt. Once in the log page, you are able to see the error
messages.
