@jianqiao No, [the distributed unit
tests](https://github.com/apache/incubator-quickstep/blob/master/query_optimizer/tests/DistributedExecutionGeneratorTestRunner.cpp#L127)
uses the same optimizer as the single node version. And since it works for the
single node, it should work for the distributed one. I will debug myself.
FYI, like what you did in `OptimizerTextTest`, I tried to disable it in the
distributed unit tests, but no luck.
