The manager would remove the server from the set of live tservers which caused the manger to treat all tablets on that tserver as assigned to dead tservers. Is it possible that the original change went just a little too far in the Manager and needs to be dialed back some? I wonder if it's possible to not treat all tablets on that tserver as assigned to dead tservers, but just stop making new assignments to those servers? -- This is an automated message from the Apache Git Service.
