bq. the master patch looks good because we have a serverAdded. In the
branch-1.4 patch looks like we only have serverChanged
In the branch-1.4 patch I only kick serverChanged in the FailedOpenUpdater if
there is a server added.

Nope, in the branch-1.4 patch I only kick serverChanged in the
FailedOpenUpdater if there is a server added.

> Any region in FAILED_OPEN state has to be manually reassigned, or the master

> cluster.
