public class TestLocalExchange
extends PlanTestBase

This test starts a Drill cluster with CLUSTER_SIZE nodes and generates data for test tables. Tests queries involve HashToRandomExchange (group by and join) and test the following. 1. Plan that has mux and demux exchanges inserted 2. Run the query and check the output record count 3. Take the plan we got in (1), use SimpleParallelizer to get PlanFragments and test that the number of partition senders in a major fragment is not more than the number of Drillbit nodes in cluster and there exists at most one partition sender per Drillbit.
