Thanks for the reply Ayush, appreciate it as always. Are you saying that default implementation of "logging and/or exposing JMX metrics" for a given datanode if it doesn't stay connected is also not feasible according to you? I know we have metric that says "lastHeartbeat" and "lastHeartbeatResponseTime" but it's still difficult for user or script to apply a loop into BP service actor metrics rather than getting as simple log or metric as "this datanode has not heard from active namenode in the last 60s or so". Are you at least fine with keeping this as default implementation logic? -- This is an automated message from the Apache Git Service.
