FailoverController Connect namenode timed out

FailoverController Connect namenode timed out

New Contributor

 

        Hi,All:

 

          I used the CDH5.5.2 version, installed the hadoop ha service, and Recently, an auto failover occurred one or more times during one day,and I found nothing useful in the logs of namenode.Only ZKFC shows the error message of a link timeout, But the port state is normal for namenode .and then the monitoring status starts to be unhealthy for ZKFC , and the cluster automatically switches after the timeout period.
