> Spent time on TestFavoredNodeTableImport. It fails w/ an NPE when we go to
> get favorednodes for one of the regions. It is sporadic. Fails for me locally
> too about 30% of the time.
> I tried to study where we are going wrong. The balancer is disabled when we
> start the cluster up again on FN balancer... but this don't seem to be the
> problem.
> Looks like laggard Regions taking their time to open means they don't show in
> the global list of favored nodes when the checking runs. Adding a wait till
> no RIT seems to stabilize the test.
