我在生产中有5个运行中的火花

Node1: Worker
Node2: Worker
Node3: Worker
Node4: Worker
Node5: Master

5个节点位于LAN网络中，只有Master Node的IP是公用的。

情况1 ：我的SQL Server节点仅在防火墙中为Node5启用连接。当用火花运行作业时，我收到此消息：

org.apache.spark.SparkException: 
Job aborted due to stage failure: Task 0 in stage 0.0 failed 4 times,most recent failure: Lost task 0.3 in stage 0.0 (TID 3,10.158.6.95,executor 2):
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host 42.113.207.214,port 1433 has failed. 
Error: "Connection timed out: no further information. 
Verify the connection properties. 
Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. 
Make sure that TCP connections to the port are not blocked by a firewall.".

情况2 ：当我的SQL-Server节点禁用防火墙，然后成功运行带有spark的作业

启用防火墙时，我从所有Worker连接到SQL Server时遇到问题。

如何设置所有Worker通过Node5通过SSH连接到SQL Server？

_{PS：我的SQL Server无法启用来自Worker的连接，因为网络不同。}
