Steps to reproduce

The hive sql submission is usually very long, and there may be dozens of entries in one file. The first few entries are set parameter commands, such as set today=current_date. After execution for dozens of minutes, the session may be interrupted, and the subsequent sql will be used again. If hiveconf:today is taken, it will be empty.

hive sql提交的时候一般都很长，可能一个文件有几十条，前面几条是set 设置参数命令，如set today=current_date,执行几十分钟后可能这个session会话中断了，后面的sql 再去取hiveconf:today就会为空

Expected behavior

support task connection cache
