Description
On rare occasions, a cluster might lose all its masters permanently, especially if there is only a single master. This would mean a total loss of the whole cluster unless the user is willing to use tools to dump the data from each tablet server, save it, and reprocess it back into a useful form again. However, in many cases, it's actually possible to reconstruct a workable master state from information on the tablet servers. A tool to do this could be a lifesaver.
