The pre-upgrade stage was added to support code / checks that are likely independent of a specific version. Checking the ZooKeeper authorizations is one example. It is not version dependent, but continuing an upgrade with potentially invalid auths seemed like it should be avoided. The ability to communicate with a tserver seems to also fit within this category. Before anything happens that is dependent on version, this check would establish a baseline of "at least I can talk to all of the registered tservers" before any version dependent code would have a chance to run. -- This is an automated message from the Apache Git Service.
