We use gauge here because 1. Normally, task generation is not a frequent event, we don't need to care about rate 2. We want to keep the error until the next successful run so that we know the problem has not been fixed. A successful run can clear out error history to indicate the problem does not exist any more. -- This is an automated message from the Apache Git Service.
