-----------------------------------
Summary: 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: Will Berkeley
Assignee: Will Berkeley
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.
