However, DNS won't be able to consider > only resolving to the working router based on certain health thresholds. > There are some ways about how this can be solved. One way is to have a > separate script to regularly check the status of the router and update the > DNS records if a router fails the health thresholds. In this way, security > might be carefully considered for this way. Another way is to have the client > do the normal connecting/failover after they get the list of routers, which > requires the change of current failover proxy provider. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
