["Todd Lipcon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KUDU-871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15454492#comment-15454492 ] 

Todd Lipcon commented on KUDU-871:
----------------------------------

Mike, did you get started on this at any point? Considering taking it up as we've seen a few cases where we do end up with occasional cases where TS A is dead (machine down), TS B is alive, and TS C has a tombstone. If TS C could vote, then B could become leader, revive C from a tablet copy, and then eventually get back up to full strength. Plus it seems like it might be relatively low-hanging fruit.

> We may need to support voting for tombstoned tablets to avoid availability issues in certain scenarios. See the remote bootstrap design document at https://docs.google.com/document/d/1zSibYnwPv9cFRnWn0ORyu2uCGB9Neb-EsF0M6AiMSEE/edit#heading=h.ftfifcm5i562 under "Should a server be allowed to vote if it DOES_NOT_EXIST or is DELETED?" for discussion.
