* For each management node, try twice at least in case of poor network situation.
* If the client start to connect to a non-management node from the client, and the first retry may fail due to
* the poor network quality. And then, the second retry get the response with redirection command.
* The retry will not be executed since only *two* retry is allowed in case of single management node in the cluster.
* Therefore, we need to multiply the retry times by factor of 2 to fix this problem.
