Todd Lipcon commented on KUDU-1391:
-----------------------------------
What version are they running? This sounds vaguely like KUDU-1338. Let me take
a look at the logs.
> 2 of 3 replica alive but failed to elect leader

> Last weekend many TS have a lot too many open files error(haven't upgrade to
> , when using our internal deploy tool to restart cluster (stop all ts, then
> start all ts), the control machine have some issue which seems to block or
> write to ssh terminal(maybe usb driver issue, not related to this bug), so
> only half (about 30) of the TS is shutdown, then after maybe 10 minutes, I
> switch to another control host and perform the whole restart.
> Then I see writes are blocked, because 1 tablet is in no leader state, from
> web-ui, 2 of 3 replicas is in follower state, 1 TABLET_DATA_TOMBSTONED, but
> all election failed, will attach the log of the 2 followers.
