------------------------------
Target Version/s: (was: 1.9.0)
> Add a tool to reconstruct master data from the tablet servers
> -------------------------------------------------------------
>
> Key: KUDU-2661
> URL: https://issues.apache.org/jira/browse/KUDU-2661
> Project: Kudu
> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: William Berkeley
> Assignee: William Berkeley
> Priority: Major
> Labels: supportability
>
> 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.
