Hive Boot prompt Port 10000 is occupied: selectchannelconnector@0.0.0.0:10000:java.net.bindexception

Problem Description:
When you use the Hive--service hiveserver2 to start the Hiveserver2 service, you are prompted to selectchannelconnector@0.0.0.0:10000:java.net.bindexception.
problem Reason:
It was started once with this command, but because it did not start successfully, I terminated the process directly with Ctrl+z and started again, so I would prompt the port to be occupied.
Solution:
Use lsof-i:10000 to view the 10000 port is occupied, if already occupied by the process, use kill-9 sessionId to kill the process directly after the restart of the Hiveserver2 service.
