DSE 图 - 主机未及时响应

Question

Gremlin 控制台似乎连接正确，但它会在任何查询后回复 "Host did not respond in a timely fashion"。

已检查： - remote.yaml - netstat --listen | grep 8182（returns 无）

Gremlin 行：

plugin activated: tinkerpop.tinkergraph
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
gremlin> :remote connect tinkerpop.server conf/remote.yaml
==>Configured localhost/127.0.0.1:8182
gremlin> :> 1+1
Host did not respond in a timely fashion - check the server status and submit again.

堆栈跟踪：

Answer 1

当您安装 DSE 时，Graph 服务会在本地网络接口中侦听（例如 10.x.x.x，而不是环回 127.0.0.1）。

这意味着您需要编辑 Gremlin 控制台 YAML 并将其指向 10.x.x.x。

Answer 2

有些人可能对此感到困惑，但如果您尝试在本地运行命令并且出现此错误，运行 :remote console 并且错误应该消失。
