NebulaGraph Exchange报错`com.facebook.thrift.protocol.TProtocolException: Expected protocol id xxx` 如何解决？

Question

NebulaGraph Exchange运行时出现如下错误：

com.facebook.thrift.protocol.TProtocolException: Expected protocol id xxx

Answer 1

检查NebulaGraph服务端口配置是否正确。

• 对于源码、RPM或DEB安装，在每个服务的配置文件中配置--port对应的端口号。

• 对于docker安装，配置docker映射端口号如下：

  在nebula-docker-compose目录下执行docker-compose ps，例如：

  $ docker-compose ps
                Name                             Command                  State                                                         Ports

  检查Ports 列以找到 docker 映射的端口号，例如：

  • Graph服务可用的端口号是9669。

  • Meta服务的端口号是33167、33168、33164。

  • 存储服务的端口号是33183、33177、33185。
