从2.1.6升级到2.1.11后，创建外部数据源，报错找不到驱动，切换回2.1.6可以正常找到。路径权限确认没问题

检查目录权限

ls -ld /opt/doris-be/jdbc_drivers/
-rw-r--r-- 1 doris doris 5040465 May 12  2025 /opt/doris-be/jdbc_drivers/ojdbc8.jar
drwxrwxrwx 2 doris doris 122 May 12  2025 /opt/doris-be/jdbc_drivers/

应用启动进程查询

doris@ECS-DorisCluster-003:/opt/doris-be/bin$ ps -ef|grep doris-be
doris     618661       1  3 11:32 pts/1    00:00:48 /opt/doris-be/lib/doris_be
