Viewing Distributed Profiling Task Errors - trillium_discovery - Latest

When you add data sources to load and analyze your data in a Hadoop cluster, the task named Distributed Profiling displays in the Task column. The distributed profiling task indicates that distributed profiling activities such as data load analysis, data profiling analysis aggregation, and key & dependency analysis in your distributed environment are in progress or have completed.

If a distributed profiling task status shows that it failed to complete, the Reason column indicates that a problem was encountered at a certain point during profiling activities.

If a Kerberos ticket in your distributed environment has expired, this can be one of the causes for the task to stop before completing. For more information about troubleshooting Kerberos tickets in your Hadoop environment, see your system administrator.

To see information about why the failure occurred, open the mtb_server.log on the repository server system. Entries in the log record the date, time, job ID value, and affected data for each activity.
