The error information is as follows

Cause analysis

The main reason is that the hive configuration file is not configured in spark. Copy the hive-site.xml file of hive configuration to the spark directory

mv ../hive/conf/hive-site.xml ../spark/conf/hive-site.xml

explain:

If a JDBC error is reported, you also need to copy the MySQL jdbc driver under ../hive/lib to the ../spark/jars directory

The jar package MySQL connector is in hive’s lib directory, and the path where spark stores Jia package is in jars directory
