RemoteTransportException, this exception reminds the user which service has a
problem by means of Ip/Port.
When we troubleshoot the problem, the information is not accurate enough.
Usually at this time we need to look at the running log of the container that
has the problem, but when we see this log, it also shows that the container has
died, so pass Ip/ The port method can no longer quickly locate a specific
container.
So I hope that when such an exception occurs, I hope to print the containerId。
E.g:
Connection unexpectedly closed by remote task manager
'hostName/ip:port/containerId'. This might indicate that the remote task
manager was lost.
