性能优化、故障排查等需要收集“系统/集群信息”的问题,请下载脚本运行。全选终端打印结果,并复制粘贴上传。 报错如下: “msg”: “[code=38033:class=dm-master:scope=internal:level=high] request is timeout, but request may be successful, please execute query-status to check statusngithub.com/pingcap/dm/pkg/terror.(*Error).Generate /home/jenkins/agent/workspace/build_dm_master/go/src/github.com/pingcap/dm/pkg/terror/terror.go:232ngithub.com/pingcap/dm/dm/master.(*Server).waitOperationOk /home/jenkins/agent/workspace/build_dm_master/go/src/github.com/pingcap/dm/dm/master/server.go:1923ngithub.com/pingcap/dm/dm/master.(*Server).handleOperationResult /home/jenkins/agent/workspace/build_dm_master/go/src/github.com/pingcap/dm/dm/master/server.go:1946ngithub.com/pingcap/dm/dm/master.(*Server).StartTask.func1 /home/jenkins/agent/workspace/build_dm_master/go/src/github.com/pingcap/dm/dm/master/server.go:276ngithub.com/pingcap/dm/dm/master.(*AgentPool).Emit /home/jenkins/agent/workspace/build_dm_master/go/src/github.com/pingcap/dm/dm/master/agent_pool.go:117 runtime.goexit /usr/local/go/src/runtime/asm_amd64.s:1337”

[code=38033:class=dm-master:scope=internal:level=high],“request to dm-worker %s is timeout, but request may be successful, please execute query-status to check status” 建议检查一下网络和 dm-worker的启动日志
