---------------------------------
Summary: add min_cost for each query
Key: HAWQ-278
URL: https://issues.apache.org/jira/browse/HAWQ-278
Project: Apache HAWQ
Issue Type: Bug
Reporter: Hubert Zhang
Assignee: Lei Chang
When we run 50 concurrancy insert into values(3) in 16 hosts.
they will run on the only one host, not balanced.
This is caused by we pass cost zero to RM for "insert into values" like query.
We need to assign a min_cost for each query.
