I’m having problems to run Engagement tasks. Running InsertToMysqlCourseActivityTask always exist with status 30 (error). It seems to be a problem injecting data into MySQL as it raise the following exception: ‘Cannot overwrite a table with an empty result set.’ Here is full InsertToMysqlCourseActivityTask log
Tracking the code, it seems that the insertion is done by CourseActivityPartitionTask, but if I run a similar hive query, it returns data and seems to do the insertion ok (see select log and overwrite log).
I am confused with the error message: if hive returns data properly, why SQL receives an empty result?
Thanks in advance for any help
