In fact my calcite server is running in port 9093，but mapd server is trying to connect 39093 and was refused.
Hi @Kigo -
Can you provide some more information? What version of MapD are you trying to install (Community, Enterprise, Open-Source) and in what environment (VM, laptop, server, cloud)?
Please see my answer here: Uninstall / Remove MapD
Let me know if that answers your question!
