> Code in the master and tserver that ends up directly calling {{System.exit}} makes it really crappy to actually test said error conditions.
> We could make a Halt interface and provide a means to inject an implementation of Halt.
> This would allow test cases to inject their own implementation that verifies that certain error conditions were reached. This would also enable the in-process MAC (ACCUMULO-2739)
