无法使用DSE 4.7查找Spark master

Question

我升级到DSE 4.7，现在Spark主地址似乎已经重置。当我尝试使用dse spark运行spark时，我得到：

java.io.IOException: Spark Master address cannot be retrieved. This really should not be happening with DSE 4.7+ unless your cluster is over 50% down or booted up in the last minute.

运行dsetool sparkmaster时出现相同的错误。是否可以在某个地方手动设置主设备？似乎有很多配置文件任何帮助赞赏。
