Connection and Running

Comply with the following specifications when connecting to the Doris and running Doris tasks:

• You are advised to use the ELB to connect to the Doris to ensure that services can be provided when the connected FE is faulty.
• When a single Doris instance or hardware fault occurs, newly submitted tasks can be successfully executed, but running tasks cannot be successfully executed when the fault occurs. Therefore, you need to retry a task when connecting to the Doris to execute the task. When the task fails due to unknown reasons, you can ensure that the newly submitted task can be successfully executed.
