Subject kafka git commit: MINOR: Use `waitUntil` to fix transient failures of ControllerFailoverTest
Date Wed, 31 May 2017 22:47:13 GMT
Repository: kafka
Updated Branches:

MINOR: Use `waitUntil` to fix transient failures of ControllerFailoverTest

Without it, it's possible that the assertion is checked before the exception
is thrown in the callback.

Closes #3182 from ijuma/fix-controller-failover-flakiness
