This article introduces running spark in idea to save to hive, but because there is no configuration of hive information, spark will run the internal hive by default. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Reason: run spark in idea and save it to hive. Since no hive information is configured, spark will run internal hive by default.

Reference address: (I tried and solved it effectively)
