U-SQL Job Timeout: No heartbeat from JM on time

We hava a U-SQL job, which runs for more than 50 hours before it finally results in an error and reaches time-out.

The job does not have any failed vertices. For troubleshooting, I opened the profile file under Resources in Visual Studio 2015 Job View. I could not find any errors/warnings.

The error is given below:

U-SQL Job Error: No heartbeat from JM on time.

How do/should I troubleshoot this error?

Solution

  • Sorry for the late reply. Any error that says that it is a system error (E_SYSTEM) should be escalated and filed as an incident for investigation.
