inetkiller opened a new issue, #850:
URL: https://github.com/apache/rocketmq-client-go/issues/850
I used the consumer code from the example, consumer does't get message from
slave when master broker down
```
package main
import (
"context"
"fmt"
"os"
"strings"
"time"
"github.com/apache/rocketmq-client-go/v2"
"github.com/apache/rocketmq-client-go/v2/consumer"
"github.com/apache/rocketmq-client-go/v2/primitive"
)
func main() {
nameservers := os.Getenv("NAMESERVERS")
c, _ := rocketmq.NewPushConsumer(
consumer.WithGroupName("testGroup"),
consumer.WithNsResolver(primitive.NewPassthroughResolver(strings.Split(nameservers,","))),
)
err := c.Subscribe("test", consumer.MessageSelector{}, func(ctx
context.Context,
msgs ...*primitive.MessageExt) (consumer.ConsumeResult, error) {
for i := range msgs {
fmt.Printf("subscribe callback, broker:%s queueID:%d
queueMaxOffset:%s queueCurrentOffset:%d \n",
msgs[i].StoreHost,msgs[i].Queue.QueueId,msgs[i].GetProperties()["MAX_OFFSET"],msgs[i].QueueOffset)
}
return consumer.ConsumeSuccess, nil
})
if err != nil {
fmt.Println(err.Error())
}
// Note: start after subscribe
err = c.Start()
if err != nil {
fmt.Println(err.Error())
os.Exit(-1)
}
time.Sleep(time.Hour*999)
err = c.Shutdown()
if err != nil {
fmt.Printf("shutdown Consumer error: %s", err.Error())
}
}
```
