> KUDU-2149 uncovered an issue where a change in failure detector semantics could lead to election "stacking". It was clear that the failure detector should be disabled during an election, but the fix was tailored to minimize risk and thus be eligible for backporting to a 1.5.x point release.
> The better fix would be to completely the disable failure detector during an election. This JIRA tracks that improvement.
