URL: https://github.com/apache/incubator-dolphinscheduler/pull/4593


   ## What is the purpose of the pull request
   this PR closes #4450 
   
   Hive/Spark JDBC supports manual configuration of keytab parameters when 
using Kerberos authentication, and supports multi-tenancy when using Kerberos 
authentication for Hive/Spark data sources.
   
   The current Hive/Spark JDBC system uses Kerberos authentication using the 
keytab configured in the common.properties file. There is a problem when 
Hive/Spark data source Kerberos authenticates other users or multiple different 
users.
